Outcomes of Transarterial Embolisation (TAE) vs. Transarterial Chemoembolisation (TACE) for Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis.

Although hepatocellular carcinoma is increasingly common, debate exists surrounding the management of patients with unresectable disease comparing transarterial embolisation (TAE) or transarterial chemoembolisation (TACE). This study aimed to compare the outcomes of patients receiving TAE and TACE. A systematic review was performed using PubMed, Medline, Embase, and Cochrane databases to identify randomised controlled trials (RCTs) until August 2021. The primary outcome was overall survival (OS) and the secondary outcomes were progression-free survival (PFS) and adverse events. Five studies with 609 patients were included in the analysis. There was no statistically significant difference in the OS (p = 0.36) and PFS (p = 0.81). There was no difference in OS among patients treated with a single TACE/TAE versus repeat treatments. Post-procedural adverse effects were higher in the TACE group but were not statistically significant. TACE has comparable long-term survival and complications profile to TAE for patients with HCC. However, the low-to-moderate quality of current RCTs warrants high-quality RCTs are necessary to provide enough evidence to give a definitive answer and inform treatment plans for the future.

Efficacy and safety of acupuncture-point stimulation combined with opioids for the treatment of moderate to severe cancer pain: a network meta-analysis of randomized controlled trials.

Pain is one of the most common and troublesome symptoms of cancer. Although potential positive effects of acupuncture-point stimulation (APS) on cancer pain have been observed, knowledge regarding the selection of the optimal APS remains unclear because of a lack of evidence from head-to-head randomized controlled trials (RCTs). This study aimed to carry out a network meta-analysis to compare the efficacy and safety of different APS combined with opioids in treating moderate to severe cancer pain and rank these methods for practical consideration. A comprehensive search of eight electronic databases was conducted to obtain RCTs involving different APS combined with opioids for moderate to severe cancer pain. Data were screened and extracted independently using predesigned forms. The quality of RCTs was appraised with the Cochrane Collaboration risk-of-bias tool. The primary outcome was the total pain relief rate. Secondary outcomes were the total incidence of adverse reactions, the incidence of nausea and vomiting, and the incidence of constipation. We applied a frequentist, fixed-effect network meta-analysis model to pool effect sizes across trials using rate ratios (RR) with their 95% confidence intervals (CI). Network meta-analysis was performed using Stata/SE 16.0. We included 48 RCTs, which consisted of 4,026 patients, and investigated nine interventions. A network meta-analysis showed that a combination of APS and opioids was superior in relieving moderate to severe cancer pain and reducing the incidence of adverse reactions such as nausea, vomiting, and constipation compared to opioids alone. The ranking of total pain relief rates was as follows: fire needle (surface under the cumulative ranking curve (SUCRA) = 91.1%), body acupuncture (SUCRA = 85.0%), point embedding (SUCRA = 67.7%), auricular acupuncture (SUCRA = 53.8%), moxibustion (SUCRA = 41.9%), transcutaneous electrical acupoint stimulation (TEAS) (SUCRA = 39.0%), electroacupuncture (SUCRA = 37.4%), and wrist-ankle acupuncture (SUCRA = 34.1%). The ranking of total incidence of adverse reactions was as follows: auricular acupuncture (SUCRA = 23.3%), electroacupuncture (SUCRA = 25.1%), fire needle (SUCRA = 27.2%), point embedding (SUCRA = 42.6%), moxibustion (SUCRA = 48.2%), body acupuncture (SUCRA = 49.8%), wrist-ankle acupuncture (SUCRA = 57.8%), TEAS (SUCRA = 76.3%), and opioids alone (SUCRA = 99.7%). APS seemed to be effective in relieving cancer pain and reducing opioid-related adverse reactions. Fire needle combined with opioids may be a promising intervention to reduce moderate to severe cancer pain as well as reduce opioid-related adverse reactions. However, the evidence was not conclusive. More high-quality trials investigating the stability of evidence levels of different interventions on cancer pain must be conducted. https://www.crd.york.ac.uk/PROSPERO/#searchadvanced, identifier CRD42022362054.

Network Meta-analysis of Qi-benefiting and blood-activating Chinese patent medicines against ischemic stroke

This study aimed to compare the efficacy of Qi-benefiting and blood-activating Chinese patent medicines in the treatment of ischemic stroke with network Meta-analysis. CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library were searched from database inception to October 2022 for randomized controlled trial(RCT) on 11 Qi-benefiting and blood-activating Chinese patent medicines in the treatment of ischemic stroke. The risk of bias plot was made by RevMan 5.3, and network Meta-analysis and efficacy ranking were performed by Stata 17. Ninety-two RCTs were included, involving 10 608 patients. According to the network Meta-analysis, in terms of the clinical total effective rate, surface under the cumulative ranking curve(SUCRA) as followed: Qilong Capsules+conventional western medicine>Zhishe Tongluo Capsules+conventional western medicine>Longshengzhi Capsules+conventional western medicine>Naoxintong Capsules+conventional western medicine>Tongsaimai Tablets+conventional western medicine>Naoan Capsules+conventional western medicine>Naoluotong Capsules+conventional western medicine>Xiaoshuan Changrong Capsules+conventional western medicine>Dengzhan Shengmai Capsules+conventional western medicine=Tongxinluo Capsules+conventional western medicine>Naomaitai Capsules+conventional western medicine. In terms of the improvement in National Institute of Health stroke scale(NIHSS) score, SUCRA as followed: Longshengzhi Capsules+conventional western medicine>Naomaitai Capsules+conventional western medicine>Naoxintong Capsules+conventional western medicine>Dengzhan Shengmai Capsules+conventional western medicine>Xiaoshuan Changrong Capsules+conventional western medicine>Naoluotong Capsules+conventional western medi-cine>Tongxinluo Capsules+conventional western medicine>Naoan Capsules+conventional western medicine>Qilong Capsules+conventional western medicine. In terms of safety, the overall adverse reactions/events of Qi-benefiting and blood-activating Chinese patent medicines + conventional western medicine were less than those of the control group. Since Qilong Capsules+conventional western medicine and Zhishe Tongluo Capsules+conventional western medicine were preferred to improve the clinical total effective rate. In the aspect of improving NIHSS score, Longshengzhi Capsules+conventional western medicine and Naomaitai Capsules+conventional western medicine were first options. Due to the lack of direct comparisons between drugs, the overall quality of RCT was not high, so more studies are needed to verify the strength of the evidence.

Thoughts on improving the design quality of acupuncture clinical randomized controlled trials

The British Medical Journal published the Acupuncture research album which carried viewpoints, expert consensus, research methods and other genres of papers, providing an authoritative reference for standardizing the design of clinical randomized controlled trial (RCT) of acupuncture and improving the quality of clinical research. Based on the experts' consensus of "acupuncture album" on RCT, combining clinical practice and the related literature reports, and many existing problems existing in the design, we, in the present paper, analyzed ways to improve the design quality of clinical RCT of acupuncture, starting from improving the methodological quality and repeatability of clinica RCT, so as to provide methodological guidance for the design of clinical trials and to promote the standardization of clinical trials of acupuncture.

Post-surgery interventions for hip fracture: a systematic review of randomized controlled trials

BackgroundInterventions provided after hip fracture surgery have been shown to reduce mortality and improve functional outcomes. While some systematic studies have evaluated the efficacy of post-surgery interventions, there lacks a systematically rigorous examination of all the post-surgery interventions which allows healthcare providers to easily identify post-operative interventions most pertinent to patient’s recovery.ObjectivesWe aim to provide an overview of the available evidence on post-surgery interventions provided in the acute, subacute and community settings to improve outcomes for patients with hip fractures.MethodsWe performed a systematic literature review guided by the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA). We included articles that were (1) randomized controlled trials (RCTs), (2) involved post-surgery interventions that were conducted in the acute, subacute or community settings and (3) conducted among older patients above 65 years old with any type of non-pathological hip fracture that was surgically treated, and who were able to walk without assistance prior to the fracture. We excluded (1) non–English language articles, (2) abstract-only publications, (3) articles with only surgical interventions, (4) articles with interventions that commenced pre-surgery or immediately upon completion of surgery or blood transfusion, (5) animal studies. Due to the large number of RCTs identified, we only included “good quality” RCTs with Jadad score ≥ 3 for data extraction and synthesis.ResultsOur literature search has identified 109 good quality RCTs on post-surgery interventions for patients with fragility hip fractures. Among the 109 RCTs, 63% of the identified RCTs (n = 69) were related to rehabilitation or medication/nutrition supplementation, with the remaining RCTs focusing on osteoporosis management, optimization of clinical management, prevention of venous thromboembolism, fall prevention, multidisciplinary approaches, discharge support, management of post-operative anemia as well as group learning and motivational interviewing. For the interventions conducted in inpatient and outpatient settings investigating medication/nutrition supplementation, all reported improvement in outcomes (ranging from reduced postoperative complications, reduced length of hospital stay, improved functional recovery, reduced mortality rate, improved bone mineral density and reduced falls), except for a study investigating anabolic steroids. RCTs involving post-discharge osteoporosis care management generally reported improved osteoporosis management except for a RCT investigating multidisciplinary post-fracture clinic led by geriatrician with physiotherapist and occupational therapist. The trials investigating group learning and motivational interviewing also reported positive outcome respectively. The other interventions yielded mixed results. The interventions in this review had minor or no side effects reported.ConclusionsThe identified RCTs regarding post-surgery interventions were heterogeneous in terms of type of interventions, settings and outcome measures. Combining interventions across inpatient and outpatient settings may be able to achieve better outcomes such as improved physical function recovery and improved nutritional status recovery. For example, nutritional supplementation could be made available for patients who have undergone hip fracture surgery in the inpatient settings, followed by post-discharge outpatient osteoporosis care management. The findings from this review can aid in clinical practice by allowing formulation of thematic program with combination of interventions as part of bundled care to improve outcome for patients who have undergone hip fracture surgery.

Reporting quality of randomized controlled trials of angina pectoris with integrated traditional Chinese and western medicine interventions: a cross-sectional study

Background and objectiveIntegrated traditional Chinese and western medicine (ITCWM), as a representative type of complex intervention, is commonly used for the treatment of angina pectoris (AP) in clinical practice. However, it is unclear whether the details of ITCWM interventions, such as rationale for selection and design, implementation and potential interactions for different therapies, were adequately reported. Therefore, this study aimed to describe the reporting characteristics and quality in randomized controlled trials (RCTs) of AP with ITCWM interventions.MethodsThrough a search of 7 electronic databases, we identified RCTs of AP with ITCWM interventions published in both English and Chinese from 1st Jan 2017 to 6th Aug 2022. The general characteristics of included studies were summarized, further, the quality of reporting was assessed based on three Checklists, including the CONSORT with 36 items (except for one item 1b about abstract), the CONSORT for abstracts (17 items), and a self-designed ITCWM-related checklist (21 items covering rationale and details of interventions, outcome assessment and analysis). The quality of RCTs published in English and Chinese, as well as journals and dissertations were also compared.ResultsA total of 451 eligible RCTs were included. For the reporting compliance, the mean score (95% Confidence Interval) of the CONSORT (72 scores in total), CONSORT for abstract (34 scores in total), and ITCWM-related (42 scores in total) checklists was 27.82 (27.44–28.19), 14.17 (13.98–14.37) and 21.06 (20.69–21.43), respectively. More than half items were evaluated as poor quality (reporting rate < 50%) among each Checklist. Moreover, the reporting quality of publications in English journals was higher than that in Chinese journals in terms of the CONSORT items. The reporting of published dissertations was better than that in journal publications regarding both the CONSORT and ITCWM-specific items.ConclusionAlthough the CONSORT appears to have enhanced the reporting of RCTs in AP, the quality of ITCWM specifics is variable and in need of improvement. Reporting guideline of the ITCWM recommendations should be developed thus to improve their quality.

Antibiotics in the non-surgical treatment of peri-implantitis.

Four electronic databases (MEDLINE via Pubmed; EMBASE via Ovid; EBSCO Dentistry and Oral Science Source), in addition to six related journals (Clinical Implant Dentistry and Related Research; Clinical Oral Implants Research; International Journal of Oral and Maxillofacial Implants; International Journal of Oral Implantology; Journal of Clinical Periodontology; Journal of Periodontology), were searched for publications until 2022. Randomised controlled trials (RCTs), evaluating the effectiveness of local or systemic antibiotics as an adjunct in the non-surgical treatment (NST) for peri-implantitis (PI), were assessed. The eligibility criteria included RCTs with a parallel group, split-mouth design and appropriate NST interventions over a three to twelve month period. Data were extracted from RCTs to capture a multitude of primary outcomes, including: implant success rate, radiographic marginal bone loss rate, periodontal health changes and PI resolution. Risk of bias assessments were made using the Cochrane Collaboration's tool, by two authors independently and in duplicate. RCTs with similar observation periods and interventions were included in the meta-analyses. Random-effects meta-analyses of mean differences or relative risks with 95% confidence intervals were calculated, in additional to data heterogeneity calibration through I2 statistics. Following the screening of 270 papers, six RCTs were included, which resulted in the evaluation of 391 patients (375 implants). Adjunctive local antibiotic therapy at disease sites showed statistically significant periodontal outcomes; improvements in success rate (risk ratio = 9.89; 95% CI 2.39-40.84), probing pocket depth (mean difference (MD) = 0.6 mm; 95% CI 0.42-0.78) and bleeding on probing (MD = 0.15%; 95% CI 0.10-0.19). Conversely, adjunctive systemic antibiotics improved probing pocket depths (MD = 1.15 mm; 95% CI 0.31-1.99) and probing attachment levels only (MD = 1.10 mm; 95% CI 0.13-2.08). Across the six included RCTs, the bone loss rate and PI resolution rate determined no significant differences between the groups; mirrored in the single studies and in the meta-analysis. Disease resolution ranged from 2 to 65%. Two of the studies were found to be at low risk of bias and four presented with some concerns. Adjunctive antibiotics aid NST. However, the heterogeneity of study methods and low quality of current RCTs evidenced, deem their role in NSTs of PI as inconclusive.

Clinical effect of Danshen decoction in patients with heart failure: A systematic review and meta-analysis of randomized controlled trials.

The incidence of heart failure (HF) is increasing year by year, posing a great threat to human health. Although pharmacotherapy has been able to significantly prolong patient survival, pharmacotherapy for HF still has limitations due to its complex pathogenesis and considerable individual variability, there is a great need to explore complementary and alternative therapies to slow down the progression of HF. Danshen decoction is used to treat several cardiovascular diseases including HF, but the efficacy of stabilization is uncertain. This meta-analysis evaluated the clinical efficacy of Danshen Decoction for the treatment of HF. The registration number assigned to this meta-analysis on the PROSPERO platform is CRD42022351918. Four databases were searched, and randomized controlled trials (RCTs) of Danshen decoction combined with conventional treatment (CT) of HF were screened, CT included medical treatments other than Danshen Decoction to which the patient was treated (including but not limited to angiotensin converting enzyme inhibitor, angiotensin receptor blocker, angiotensin receptor neprilysin inhibitors, β-blockers, diuretics, mineralcorticoid recept antagonist etc.). The clinical efficacy rate (CER), left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic diameter (LVESD), brain natriuretic peptide (BNP), N-terminal pro-B type natriuretic peptide (NT-proBNP) and hypersensitive C-reactive protein (hs-CRP) were included as outcome indicators. The GRADE grading scale was used to grade the above indicators. The Cochrane risk-of-bias tool and the Jadad quality scale were used to assess the methodological quality of RCTs. Finally, RevMan V.4.5 software was used for data synthesis, 95% confidence intervals (CI) for dichotomous data, risk ratios (RR), and mean differences (MD) for continuous variables were calculated, Chi-square and I2 were used for heterogeneity assessment. Nine RCTs with a total of 855 patients were included in this study, and all included RCTs had a low overall quality risk of bias and high quality of reported information. The results of the meta-analysis showed that compared with the use of CT, CER (%) was significantly improved due to Danshen decoction combined with CT (MD = 3.95, 95% CI [2.58, 6.04], P < 0.00001), LVEF (%) was significantly improved (MD = 5.46, 95% CI [5.32, 5.60], P < 0.00001), LVEDD (mm) was significantly reduced (MD = -5.27, 95% CI [-6.21, -4.32], P < 0.00001), LVESD (mm) was significantly reduced (MD = -4.60, 95% CI [-5.87, -3.32], P < 0.00001), BNP (pg/mL) was significantly reduced (MD = -88.61, 95% CI [-121.98, -55.24], P < 0.00001), NT-proBNP (pg/mL) was significantly decreased (SMD = -3.33, 95% CI [-5.92, -0.73], P = 0.01), hs-CRP (mg/L) was significantly decreased (MD = -2.73, 95% CI [-4.11, -1.34], P = 0.0001). The quality of the GRADE evidence for all outcomes was moderate to low and no RCTs reported adverse events. Our research demonstrates that Danshen decoction is an effective and safe treatment option for HF. Nevertheless, considering the limitations of methodological and the quality of RCTs, more rigorous, large-scale, multicenter randomized clinical trials are needed to further evaluate the efficacy and safety of Danshen decoction in the treatment of HF patients.

Methodological quality of randomized controlled trials of home-based rehabilitation in knee osteoarthritis: A cross-sectional survey

Background/Aim: This study aimed to evaluate the methodological quality of randomized controlled trials (RCTs) that examine home-based rehabilitation (HBR) trials for knee osteoarthritis (KOA) using the Physiotherapy Evidence Database (PEDro) scale and the nine methodology-related items of the Consolidated Standards of Reporting Trials (CONSORT) 2010 statement.&#x0D; Methods: Three electronic databases were scanned from baseline to October 10, 2021. Two reviewers independently evaluated the articles according to the two inclusion criteria: (1) in individuals diagnosed with KOA, at least one group received home-based rehabilitation as a study intervention and (2) at least one group received a comparison intervention or no intervention. The methodological quality of the included studies (n=22) was assessed using the PEDro scale and nine items of the CONSORT 2010 statement.&#x0D; Results: Among 1557 RCTs, 22 studies that fulfilled our criteria were included in the review. The mean PEDro scale score was 5.77 (1.54). This result reflects moderate methodological quality. Concealed allocation (6; 27.3%), blinding of subjects (4; 18.2%), and (0; 0.0%) of therapists associated with the methodological quality were not reported in most studies. An author’s expertise in epidemiology and/or statistics was 0.78 points (95% confidence interval [CI] 0.11–1.44), the multicenter study 0.94 points (95% CI: 0.19–1.68), and a one-unit increase in the total score of the CONSORT statement led to an increase in methodological quality of 0.55 points (95% CI: 0.34–0.76).&#x0D; Conclusion: The methodological quality of most RCTs examining HBR in KOA that we included in our systematic review was moderate. The adherence of journals and authors to CONSORT checklists in reporting of studies may lead to an improvement in the methodological quality of future published studies.

Trends and quality of randomized controlled trials on acupuncture conducted in Japan by decade from the 1960s to the 2010s: a systematic review

BackgroundMore new randomized controlled trials (RCTs) on acupuncture have been published in Japan since our last updated systematic review (2010). This systematic review aimed to evaluate the quality of RCTs on acupuncture conducted in Japan and understand the decade-wise changes in the methodological characteristics of the relevant RCTs.MethodsThe literature search was performed using Ichushi Web, the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed and our team’s compilation of relevant papers. We included full-length papers reporting RCTs that examined the clinical effects of acupuncture on patients in Japan published in or before 2019. We assessed the risk of bias (RoB), sample size, control setting, negative trial reporting, informed consent, ethics approval, trial registration, and adverse event reporting.ResultsA total of 99 articles reporting 108 eligible RCTs were identified. The number of RCTs published in each decade was 1, 6, 9, 5, 40, and 47 in the 1960s, 1970s, 1980s, 1990s, 2000s, and 2010s, respectively. Quality assessment using the Cochrane RoB tool revealed that “sequence generation” improved in and after 1990 (73%–80% of RCTs were rated as “low”) and “blinding of outcome assessors” slightly improved in and after the 2000s (40%–50% judged as “low”). However, “high” or “unclear” remained the dominant grades in other domains. Clinical trial registration and adverse events were reported only in 9% and 28% of the included RCTs even in the 2010s, respectively. A different acupuncture method or different point selection (e.g., deep vs. shallow insertion) was the most dominant control setting before 1990, while sham (or “placebo”) needling and/or sham acupoints became the most dominant in the 2000s. The proportion of RCTs with positive results was 80% in the 2000s and 69% in the 2010s.ConclusionsThe quality of RCTs on acupuncture conducted in Japan did not appear to have improved over the decades except for “sequence generation.” While the culture of submitting negative trial reports was prevalent in the Japanese acupuncture research milieu as late as the 1990s, the overall quality of the relevant trials needs to be further improved.

Cost Effectiveness of Physiotherapy Services for Chronic Condition Management: A Systematic Review of Economic Evaluations Conducted Alongside Randomized Controlled Trials

Purpose: To determine the cost-effectiveness of physiotherapy (PT) to manage individuals with chronic conditions. Method: Design: Systematic review of randomized controlled trials (RCTs). Eligibility: RCTs with adult participants diagnosed with ≥1 chronic condition, an intervention delivered or supervised by a physiotherapist, including an economic evaluation of the intervention provided. Procedure: Eight databases were searched. Title/abstract screening, full-text review, and data extraction were performed in duplicate. The quality of included studies was assessed using Cochrane's Risk of Bias Assessment 2.0. Results: Fifty-three articles were included in this review. Fifteen compared PT to no PT, 38 compared novel PT to conventional PT. Of the studies comparing PT to no PT, 53% found PT to be cost-effective. Of the studies comparing novel to conventional PT, 55% found novel interventions were cost-effective. Overall, PT was cost-effective in most studies related to arthritis, chronic LBP, and chronic neck pain. The heterogeneity of study characteristics limited the ability to perform a meta-analysis. Conclusions: Over half of included studies reported PT to be cost-effective. Future high quality RCTs performing rigorous economic evaluations are needed to determine the cost-effectiveness of different interventions delivered or supervised by a PT to prevent disability for those with chronic conditions.

A systematic review and meta-analysis of the use of methylene blue to improve the lymph node harvest in rectal cancer surgery.

Methylene blue staining of the resected specimen has been described as an alternative to the conventional palpation and visual inspection method to improve lymph node harvest. This meta-analysis evaluates the usefulness of this technique in surgery for rectal cancer, particularly after neoadjuvant therapy. Randomized controlled trials (RCTs) comparing lymph node harvest in methylene blue-stained rectal specimens to those of unstained specimens were identified from the Medline, Embase, and Cochrane databases. Non-randomized studies and those with only colonic resections were excluded. The quality of RCTs was assessed using Cochrane's risk of bias tool. A weighted mean difference (WMD) was calculated for overall harvest, harvest after neoadjuvant therapy, and metastatic nodal yield. In contrast, the risk difference (RD) was calculated to compare yields of less than 12 lymph nodes between the stained and unstained specimens. Study selection comprised seven RCTs with 343 patients in the unstained group and 337 in the stained group. Overall lymph node harvest and harvest after neoadjuvant therapy were significantly higher in stained specimens with a WMD of 13.4 and 10.6 and a 95% confidence interval (CI) of 9.5-17.2 and 4.8-16.3, respectively. Harvest of metastatic lymph nodes was significantly higher in the stained group (WMD 1.0, 95%CI 0.6-1.4). The yield of less than 12 lymph nodes was significantly higher in the unstained group with RD of 0.292 and 95% CI of 0.182-0.403. Despite a small number of patients, this meta-analysis confirms improved lymph node harvest in surgical specimens stained with methylene blue compared with unstained specimens.

Evaluation of the report quality of Chinese and English randomized controlled trials of acupuncture based on CONSORT statement and STRICTA checklist

To evaluate the report quality of Chinese and English randomized controlled trials (RCTs) of acupuncture based on the CONSORT statement and STRICTA checklist. The Chinese and English RCTs of acupuncture published from January 1, 2015 to December 31, 2019 were searched in 7 databases including PubMed. The report quality of the included RCTs was evaluated with the CONSORT 2010 statement and STRICTA checklist. A total of 506 Chinese RCTs and 76 English RCTs were included. According to the CONSORT statement, in Chinese RCTs, the items with report rate less than 50% accounted for 78.38% of all items, and the report rate of 25 items, such as background and reason, study design, outcome index, and sample size, was less than 10%. In English RCTs, the items with report rate less than 50% accounted for 35.14% of all items, and 5 items had a report rate of less than 10%. The difference of the report rate of 15 items, such as background, reason and study design, was more than 50% between Chinese and English RCTs. The report rate of all items of STRICTA checklist was relatively high in both Chinese and English RCTs. In Chinese RCTs, the items with report rate less than 50% accounted for 29.41% of all items, which included acupuncture rationale and depth of insertion. In English RCTs, only two items had a report rate less than 50%, which were acupuncture rationale, setting and context of treatment. The report rate of five items, including needle retention time, frequency and duration of treatment sessions, details of other interventions administered to the acupuncture group, setting and context of treatment, and precise description of the control or comparator in Chinese RCTs, were higher than in English RCTs. The report quality of Chinese acupuncture RCT needs to be improved urgently, and corresponding measures should be taken to further standardize the writing and reporting of acupuncture clinical research.

Comparison of Anterior Cruciate Ligament Reconstruction With Versus Without Anterolateral Augmentation: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

It is clear that the anterolateral ligament has an important role in rotational knee stability. However, whether patients undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) can benefit from anterolateral augmentation (ALA) is still controversial. To compare the effects of isolated ACLR versus ACLR combined with ALA (ACLR+ALA) on clinical outcomes and knee stability. Systematic review; Level of evidence, 1. The methodology followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search of the PubMed, Embase, and Cochrane Library Central Register of Controlled Trials databases was undertaken to identify all randomized controlled trials (RCTs) comparing isolated ACLR with ACLR+ALA for the treatment of ACL injuries in the last 15 years. The Cochrane Collaboration risk-of-bias tool and the revised Jadad scale were utilized by 2 independent reviewers to determine the quality of RCTs. Relevant data were extracted and compared between procedures, and heterogeneity across the RCTs was assessed using the I 2 statistic. The initial search yielded 849 articles. A total of 14 studies (1850 patients; 941 ACLR and 909 ACLR+ALA) satisfied the eligibility criteria for the meta-analysis. There were no significant differences between the procedures in terms of patient-reported outcomes (International Knee Documentation Committee score, Tegner score, Knee injury and Osteoarthritis Outcome Score) or return-to-sport rates. However, patients who underwent ACLR+ALA had better knee stability based on the pivot-shift test (risk ratio [RR], 1.06 [95% CI, 1.02 to 1.10]; P = .0008), Lachman test (RR, 1.03 [95% CI, 1.00 to 1.07]; P = .04), and side-to-side difference in anterior laxity (standardized mean difference, -0.55 [95% CI, -0.98 to -0.12]; P = .01) as well as a lower incidence of graft failure (RR, 0.30 [95% CI, 0.19 to 0.45]; P < .01) compared with patients who underwent isolated ACLR. ALA can be considered as a reinforcement of ACLR to improve anteroposterior and anterolateral rotational stability of the knee and reduce the risk of failure. The patient-reported outcomes of isolated ACLR were similar to those of ACLR+ALA, and both procedures provided improved knee function.

Analysis of the reports of low-concentration atropine in controlling myopia in children

To evaluate the efficacy of 0.01% atropine to slow the progression of myopia in children. We searched PubMed, Embase, ClinicalTrials.gov, CNKI, Cqvip and Wan fang databases from inception to January 2022, including RCTs (randomized controlled trials) and non-RCTs (non-randomized controlled trials). The search strategy was 'myopia' OR 'refractive error' and 'atropine.' Two researchers independently reviewed the articles, and stata12.0 was used for meta-analysis. The Jadad score was used to assess the quality of RCT, and the Newcastle-Ottawa scale was used for non-RCTs. Five RCTs and two non-RCTs (1 prospective non-randomized controlled study, 1 retrospective cohort study) were identified (including 1000 eyes). Results of the meta-analysis showed statistical heterogeneity among the 7 included studies (P=0. 026, I2 =47.1%). According to different durations of atropine use-4 months, 6 months and greater than 8 months, subgroup analysis results showed that the axial elongation of all experimental groups relative to control groups were respectively -0.03mm (95% [CI], (confidence interval), -0.07 to 0.01), -0.07mm (95% [CI], -0.10 to -0.05), -0.09mm (95% [CI], -0.12 to -0.06). Each P was greater than 0.05, which indicated that there is little heterogeneity among the subgroups. In this meta-analysis of the short-term efficacy of atropine in myopia patients, it was found that there was little heterogeneity when grouped by usage time. It is suggested that the use of atropine in the treatment of myopia is not only related to its concentration but also related to the duration of use.

Comparative Effects of 11 Antipsychotics on Weight Gain and Metabolic Function in Patients With Acute Schizophrenia: A Dose-Response Meta-Analysis.

Objective: To investigate the association of metabolic side effects with antipsychotic dose, we conducted a dose-response meta-analysis of randomized controlled trials (RCTs) in which antipsychotics were administered to people with schizophrenia. The primary outcome was mean change in weight. The secondary outcomes were the mean changes in metabolic parameters.Data Sources: MEDLINE, Embase, PubMed, PsyARTICLES, PsycINFO, Cochrane Database of Systematic Reviews, and different trial registries were searched for articles published in English until February 2021.Study Selection: We identified fixed-dose RCTs with first- or second-generation antipsychotics. The quality of RCTs was measured with Cochrane's Risk of Bias tool.Data Extraction: We performed a dose-response meta-analysis.Results: We retained 52 RCTs including 22,588 participants. With the exception of aripiprazole long-acting injectable (LAI), all investigated antipsychotics presented significant dose-response associations with weight, from lurasidone with a quasi-parabolic shaped curve (9 studies, estimation of 95% effective dose [ED95; 59.93 mg/d] = 0.53 kg/6 wk) to olanzapine LAI with a curve that continued to increase with the dose (1 study, ED95 [15.05 mg/d] = 4.29 kg/8 wk). All curves could be ordered in 3 different classes of shapes-quasi-parabolic, plateau, and ascending.Conclusions: We found significant dose-response associations for weight and metabolic variables, with a unique signature for each antipsychotic. Weight gain can occur at a relatively low median effective dose, and increasing doses can be associated with greater weight gain for some drugs. Despite several limitations, including the limited number of available studies, our results may provide useful information for preventing weight gain and metabolic disturbance by adapting antipsychotic doses.Registration: PROSPERO ID number CRD42021176569.

Is chewable toothbrush effective in terms of dental plaque reduction in children? A systematic review and meta-analysis of randomized controlled trials.

To systematically evaluate randomized controlled trials (RCTs) on whether a chewable toothbrush (CTB) is more effective than a manual toothbrush (MTB) in terms of full-mouth dental plaque reduction in non-orthodontic children. Six databases were searched by two independent reviewers according to pre-specified eligibility criteria up to October 2022. No restrictions regarding language, date of publication and minimum follow-up period were imposed. The Cochrane Collaboration's Risk of Bias tool (RoB 2.0) was used for quality appraisal and GRADE for assessing the certainty of evidence. Random-effects pairwise meta-analysis compared the dental plaque change scores of CTB and MTB through mean differences (MDs) and associated confidence intervals (95% CI), and sensitivity analysis determined whether an individual study significantly affected the results. Seven eligible RCTs were retrieved, including data of 310 children aged 8-14 years. Five RCTs present some concerns and two have high RoB. No significant difference was detected between toothbrushes in terms of Turesky modification of the Quigley-Hein plaque index reduction (MD=-0.04, 95% CI: -0.26-0.18), with overall very low certainty on evidence. The pooled estimate remains unchanged when any RCT is omitted. There is very low-certainty evidence of no significant difference on plaque removal between MTB and CTB in non-orthodontic children. Due to unexplained high heterogeneity and low methodological quality of RCTs, we cannot determine the extent to which our finding reflects a true effect or bias arising from limitations of primary studies.

Could patients with chronic obstructive pulmonary disease benefit from renin angiotensin system inhibitors? A meta-analysis

BackgroundChronic obstructive pulmonary disease (COPD) is considered related to chronic systemic inflammation. Renin angiotensin system (RAS) inhibitor, exerting an anti-inflammatory action in many systems, has been demonstrated relevant to the...

Efficacy of concentrated growth factor combined with grafting materials vs. grafting materials alone for the treatment of periodontal intrabony defects: a systematic review and meta-analysis.

Concentrated growth factor (CGF) is a novel biomaterial that can effectively promote tissue growth, but it is uncertain whether adding CGF can product additional effects in the periodontal tissue growth. The purpose of this meta-analysis was to assess the efficacy of CGF combined with grafting materials versus grafting materials alone for the treatment of periodontal intrabony defects. The PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), China Biology Medicine Disc (CBM), Wanfang, and VIP databases were searched from inception date to June 2022. The inclusion criteria were: (I) randomized controlled trials (RCTs) comparing CGF combined with grafting materials with the single use of grafting materials for the treatment of periodontal intrabony defects, (II) studies providing outcomes of probing depth (PD) and clinical attachment loss (CAL). The literature searches and screening, data extraction, and quality assessment were performed by two reviewers, respectively. The Cochrane bias risk assessment tool was used to assess the quality of the literature. Meta-analysis was performed using Stata 15.0. A total of 8 randomized controlled trials (RCTs) were obtained, including 150 intrabony defect sites in the combination groups and 153 sites in the control groups. Meta-analysis showed that the combination groups was more effective than the control groups in PD [weighted mean difference (WMD) =-0.73, 95% confidence interval (CI): -0.94, -0.51, P=0.005], CAL (WMD =-0.56, 95% CI: -0.94, -0.19, P=0.003), and bone filling (BF) (WMD =-0.43, 95% CI: -0.65, -0.21, P=0.001), but the difference was not statistically significant between two groups in the change of gingival recession (REC) (WMD =-0.15, 95% CI: -0.44, 0.14, P=0.312). One study presented a high risk of bias due to lost follow-up, and the rest were unclear risk of bias. For the treatment of periodontal intrabony defects, our meta-analysis showed that CGF combined with grafting materials was more effective than the use of grafting materials alone. However, the findings should be interpreted with caution due to the average quality of RCTs.
