CHA2DS2-VASc score predicts periprocedural complications and mortality of percutaneous coronary intervention irrespective of atrial fibrillation: a systematic review and meta-analysis

Abstract Funding Acknowledgements None. Background Periprocedural complications of Percutaneous Coronary Intervention (PCI) are dreaded as they negatively impact prognosis, but they are hard to predict especially in resource-limited settings. CHA2DS2-VASc Score, apart from predicting thromboembolic risk in atrial fibrillation, has been reported to be associated with several complications of PCI. Purpose We aimed to assess the predictive value of CHA2DS2-VASc score for periprocedural complications and mortality in Acute Coronary Syndrome (ACS) patients treated with PCI. Methods Systematic search of the literature was conducted through Pubmed and Embase for all articles published from inception until 24th September 2023. Studies were included if they were observational studies conducted in ACS patients who received PCI during index hospital stay and evaluated the value of CHA2DS2-VASc score to predict at least one outcome of interest. Studies were excluded if they only used modified CHA2DS2-VASc score or did not conduct a separate analysis for ACS patients. Results Out of 1,783 manually reviewed unique studies, 34 studies involving a total of 342,141 ACS patients were included. Only 2 studies exclusively included patients with atrial fibrillation. Random effect meta-analyses found a significant association between high CHA2DS2-VASc score and Contrast-Induced Nephropathy/CIN (11 studies; OR 5.35; 95%CI 3.56–8.03; I2=94%), no-reflow phenomenon (14 studies; OR 3.21; 95%CI 2.20–4.68; I2 = 91%), acute stent thrombosis (3 studies; OR 5.23; 95%CI 3.85–7.10; I2=0%), in-hospital all-cause mortality (9 studies; OR 3.25; 95%CI 1.65–6.44; I2=91%), in-hospital cardiovascular mortality (3 studies; 3.05; 95%CI 1.58–5.87; I2=38%), post-discharge all-cause mortality (4 studies; 3.35; 95%CI 2.24–5.02; I2=0%), and post-discharge cardiovascular mortality (3 studies; 3.65; 95%CI 2.65–5.01; I2=35%). The CHA2DS2-VASc score cut-off with the highest OR for each outcome was used in bivariate random-effects meta-analysis model for diagnostic test accuracy. CHA2DS2-VASc score cut-off of ≥4 is a good predictor of CIN/AKI (5 studies) with AUC 0.81 (0.77–0.84), sensitivity 0.70 (0.51–0.84), specificity of 0.81 (0.54–0.94), while CHA2DS2-VASc score cut-off of ≥2 is good for screening no-reflow phenomenon (5 studies) with AUC 0.70 (0.66–0.74), sensitivity 0.86 (0.56–0.97), specificity 0.44 (0.20–0.71), and for screening in-hospital all-cause mortality (5 studies) with AUC 0.77 (0.73–0.81), sensitivity 0.88 (0.77–0.94), and specificity 0.35 (0.19–0.55). Conclusion CHA2DS2-VASc score is a rapid, non-invasive, and easily measurable tool that provides a good prediction of CIN/AKI, as well as a useful screening tool for no-reflow phenomenon and in-hospital all-cause mortality in ACS patients who received PCI regardless of their atrial fibrillation diagnosis.CHA2DS2-VASc score cut-off 4 for CIN/AKICHA2DS2-VASc cut-off 2 for no-reflow

Network meta-analysis for an ordinal outcome when outcome categorization varies across trials

BackgroundBinary outcomes are likely the most common in randomized controlled trials, but ordinal outcomes can also be of interest. For example, rather than simply collecting data on diseased versus healthy study subjects, investigators may collect information on the severity of disease, with no disease, mild, moderate, and severe disease as possible levels of the outcome. While some investigators may be interested in all levels of the ordinal variable, others may combine levels that are not of particular interest. Therefore, when research synthesizers subsequently conduct a network meta-analysis on a network of trials for which an ordinal outcome was measured, they may encounter a network in which outcome categorization varies across trials.MethodsThe standard method for network meta-analysis for an ordinal outcome based on a multinomial generalized linear model is not designed to accommodate the multiple outcome categorizations that might occur across trials. In this paper, we propose a network meta-analysis model for an ordinal outcome that allows for multiple categorizations. The proposed model incorporates the partial information provided by trials that combine levels through modification of the multinomial likelihoods of the affected arms, allowing for all available data to be considered in estimation of the comparative effect parameters. A Bayesian fixed effect model is used throughout, where the ordinality of the outcome is accounted for through the use of the adjacent-categories logit link.ResultsWe illustrate the method by analyzing a real network of trials on the use of antibiotics aimed at preventing liver abscesses in beef cattle and explore properties of the estimates of the comparative effect parameters through simulation. We find that even with the categorization of the levels varying across trials, the magnitudes of the biases are relatively small and that under a large sample size, the root mean square errors become small as well.ConclusionsOur proposed method to conduct a network meta-analysis for an ordinal outcome when the categorization of the outcome varies across trials, which utilizes the adjacent-categories logit link, performs well in estimation. Because the method considers all available data in a single estimation, it will be particularly useful to research synthesizers when the network of interest has only a limited number of trials for each categorization of the outcome.

Efficacy and safety of onasemnogene abeparvovec for the treatment of patients with spinal muscular atrophy type 1: A systematic review with meta-analysis.

Onasemnogene abeparvovec has been approved for the treatment of spinal muscular atrophy 5q type 1 in several countries, which calls for an independent assessment of the evidence regarding efficacy and safety. Conduct a meta-analysis to assess the efficacy and safety of onasemnogene abeparvovec in patients diagnosed with SMA type 1, based on the available evidence. This article results from searches conducted on databases up to November 2022. Outcomes of interest were global survival and event-free survival, improvement in motor function and treatment-related adverse events. Risk of bias assessment and certainty of evidence were performed for each outcome. Proportional meta-analysis models were performed when applicable. Four reports of three open-label, non-comparative clinical trials covering 67 patients were included. Meta-analyses of data available in a 12-month follow-up estimate a global survival of 97.56% (95%CI: 92.55 to 99.86, I2 = 0%, n = 67), an event-free survival of 96.5% (95%CI: 90.76 to 99.54, I2 = 32%, n = 66) and a CHOP-INTEND score ≥ 40 points proportion of 87.28% (95%CI: 69.81 to 97.83, I2 = 69%, n = 67). Proportion of 52.64% (95%CI: 27.11 to 77.45, I2 = 78%, n = 67) of treatment-related adverse events was estimated. The results indicate a potential change in the natural history of type 1 SMA, but the methodological limitations of the studies make the real extent of the technology's long-term benefits uncertain.

Technological Capabilities on Business Outcomes: Evidence from Meta-Analysis and FsQCA

ABSTRACT A meta-analysis of 161 empirical studies analyzed technological capabilities (TC) through meta-analytical structure equation modeling (MASEM) and fuzzy-set qualitative comparative analysis (fsQCA). Our findings show that TC has mean positive effect size estimates across business outcomes. The combinative approach of TC presents different insights about its impact on various business outcomes. This approach highlights a theoretical view while attempting to understand the impact of TC on business outcomes.

A comparison of univariate and meta-analytic structural equation modeling approaches to reliability generalization applied to the Maslach Burnout Inventory.

Reliability is a property of tests scores that varies from sample to sample. One way of generalizing reliability of a test is to perform a meta-analysis on some reliability estimator. In 2011, a reliability generalization meta-analysis on the Maslach Burnout Inventory (MBI) was conducted, concluding that average alpha values for the MBI dimensions ranged from 0.71 to 0.88. In the present study, we aimed to update the average reliability values of the MBI by conducting a literature search from 2010 until now and comparing to statistical procedures of meta-analysis: the Univariate approach, that were used in the previous study, and a novel meta-analytic approach based on structural equation modeling. An estimation of average reliability was done based on 69 independent primary reliability coefficients for the Univariate approach. The average reliability was based on 9 independent studies in the case of the Meta-analytic Structural Equation Modeling (MASEM) approach. Given that MASEM has the additional capability of testing the internal structure of a test, we also fitted several models. The data was well-suited to the bifactor model, revealing the dominance of the general factor over the domain-specific ones. Acceptable overall alpha and omega coefficients were achieved for the two of the MBI dimensions, having depersonalization reliability estimates below recommendations. In general, the MBI can be viewed as a highly interconnected three-factor scale, being its appropriate for research purposes.

Systematic Review and Meta-Analysis: Effects of Pharmacological Treatment for Attention-Deficit/Hyperactivity Disorder on Quality of Life

We conducted a systematic review and meta-analysis to quantify the effect of attention-deficit/hyperactivity disorder (ADHD) medication on quality of life (QoL), and to understand whether this effect differs between stimulants and non-stimulants. From the dataset of a published network meta-analysis (Cortese etal., 20181), updated on 27th February 2023 (https://med-adhd.org/), we identified randomized controlled trials (RCTs) of ADHD medications for individuals aged 6 years or more with a diagnosis of ADHD based on the DSM (from third to fifth editions) or the International Classification of Diseases (ICD; ninth or tenth revision), reporting data on QoL (measured with a validated scale). The risk of bias for each RCTs was assessed using the Cochrane Risk of Bias tool 2. Multi-level meta-analytic models were conducted with R 4.3.1. We included 17 RCTs (5,388 participants in total; 56% randomized to active medication) in the meta-analyses. We found that amphetamines (Hedge's g= 0.51, 95% CI= 0.08, 0.94), methylphenidate (0.38; 0.23, 0.54), and atomoxetine (0.30; 0.19, 0.40) were significantly more efficacious than placebo in improving QoL in people with ADHD, with moderate effect size. For atomoxetine, these effects were not moderated by the length of intervention, and did not differ between children/adolescents and adults. In addition to being efficacious in reducing ADHD core symptom severity, both stimulant and non-stimulant medications are efficacious in improving QoL in people with ADHD, albeit with lower effect sizes. Future research should explore whether, and to what degree, combining pharmacological and non-pharmacological interventions is likely to further improve QoL in people with ADHD.

Is there a bilingual advantage in auditory attention among children? A systematic review and meta-analysis of standardized auditory attention tests.

A wealth of research has investigated the associations between bilingualism and cognition, especially in regards to executive function. Some developmental studies reveal different cognitive profiles between monolinguals and bilinguals in visual or audio-visual attention tasks, which might stem from their attention allocation differences. Yet, whether such distinction exists in the auditory domain alone is unknown. In this study, we compared differences in auditory attention, measured by standardized tests, between monolingual and bilingual children. A comprehensive literature search was conducted in three electronic databases: OVID Medline, OVID PsycInfo, and EBSCO CINAHL. Twenty studies using standardized tests to assess auditory attention in monolingual and bilingual participants aged less than 18 years were identified. We assessed the quality of these studies using a scoring tool for evaluating primary research. For statistical analysis, we pooled the effect size in a random-effects meta-analytic model, where between-study heterogeneity was quantified using the I2 statistic. No substantial publication bias was observed based on the funnel plot. Further, meta-regression modelling suggests that test measure (accuracy vs. response times) significantly affected the studies' effect sizes whereas other factors (e.g., participant age, stimulus type) did not. Specifically, studies reporting accuracy observed marginally greater accuracy in bilinguals (g = 0.10), whereas those reporting response times indicated faster latency in monolinguals (g = -0.34). There was little difference between monolingual and bilingual children's performance on standardized auditory attention tests. We also found that studies tend to include a wide variety of bilingual children but report limited language background information of the participants. This, unfortunately, limits the potential theoretical contributions of the reviewed studies. Recommendations to improve the quality of future research are discussed.

Examining the linkage between managerial ties and firm performance: The mediating role of marketing capabilities and moderation role of industry - A meta-analytic approach

This paper investigates the relationship between managerial ties (business and political ties) and firm performance (operational performance and innovation). We consider marketing capabilities as a mediating variable to analyze how it mediates the relationship between managerial ties and firm performance. Previous studies have often taken a piecemeal approach to examining the ties-performance linkage and have been limited by sample size. We use a meta-analytic structural equation modeling (meta-SEM) approach to analyze the proposed relationship. We consider 281 studies assessing 943,331 effect sizes to analyze the results. To investigate the relationship, we consider social exchange and resource-based theory. The results suggest that business (political) ties are positively (negatively) associated with operational performance, while both business and political ties are positively associated with innovation. Further, our result suggests that (a) approximately 14.2% of the effect of business ties on innovation is mediated by marketing capabilities and (b) industry type moderates the relationship between ties and performance. This study helps managers leverage managerial ties to improve firm performance and further suggests a proper mechanism through which firms can improve performance.

Treatment of Warthin's Tumors of the Parotid Gland With Radiofrequency Ablation: A Systematic Review of the Current Literature.

Objective: Warthin's tumors of the parotid gland can be safely observed. Definitive treatment usually requires parotidectomy under general anesthesia. The decision to operate on Warthin's tumors of the parotid gland can be complicated in patients who wish to avoid risks of surgery and general anesthesia. This systematic review explores the potential of radiofrequency ablation (RFA) as a minimally invasive alternative. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model was used to collect 3 relevant studies that focused on RFA treatment for Warthin's tumors. The cumulative averages for tumor size and cosmetic scores were then quantified for patients with Warthin's tumors who underwent RFA therapy. The PRISMA systematic review method was employed to the PubMed and EMBASE databases. The comprehensive search term "Warthin Tumor Treatment" yielded 1299 articles from the years 1955 to 2023, 3 of which met inclusion criteria and were then selected. Results: The 3 quantitative studies collectively assessed 37 patients with Warthin's tumors treated with RFA. Patients experienced an average tumor size reduction of 85.03% at 12 months post-RFA. There were minimal complications associated with RFA in these patients. Conclusion: This study suggests that RFA is an alternative to parotidectomy for the symptomatic treatment of Warthin's tumors. RFA procedures demonstrated substantial tumor size reduction with few complications. However, further meta-analysis and comparison with alternative treatments is warranted to establish RFA's role in treatment of Warthin's tumors. The study is limited by its reliance on only 2 databases and a lack of comprehensive examination of different RFA settings.

Tourist engagement: Toward an integrated framework using meta-analysis

Tourist engagement (TE) has gained prominence in academia and industry. While previous studies have focused on exploring TE in tourism and hospitality, no consolidated empirical study has been conducted. We conducted a comprehensive meta-analysis using data from 73 independent studies retrieved from 72 papers, with a total sample size of 41,757. Our analysis, using meta-analytic structural equation modelling, tested a conceptual framework and found that tourist experience and TE individually mediate tourists’ satisfaction, emotion, behavioral intention, and loyalty. Additionally, cultural (e.g., power distance, individualism, uncertainty avoidance, indulgence) and economic (e.g., human development index) moderators influence TE. Our findings also suggest that popular global destinations enhance the relationship between tourist experience, engagement, and behavioral intention.

Contributions of the left and right thalami to language: A meta-analytic approach.

Despite a pervasive cortico-centric view in cognitive neuroscience, subcortical structures including the thalamus have been shown to be increasingly involved in higher cognitive functions. Previous structural and functional imaging studies demonstrated cortico-thalamo-cortical loops which may support various cognitive functions including language. However, large-scale functional connectivity of the thalamus during language tasks has not been examined before. The present study employed meta-analytic connectivity modeling to identify language-related coactivation patterns of the left and right thalami. The left and right thalami were used as regions of interest to search the BrainMap functional database for neuroimaging experiments with healthy participants reporting language-related activations in each region of interest. Activation likelihood estimation analyses were then carried out on the foci extracted from the identified studies to estimate functional convergence for each thalamus. A functional decoding analysis based on the same database was conducted to characterize thalamic contributions to different language functions. The results revealed bilateral frontotemporal and bilateral subcortical (basal ganglia) coactivation patterns for both the left and right thalami, and also right cerebellar coactivations for the left thalamus, during language processing. In light of previous empirical studies and theoretical frameworks, the present connectivity and functional decoding findings suggest that cortico-subcortical-cerebellar-cortical loops modulate and fine-tune information transfer within the bilateral frontotemporal cortices during language processing, especially during production and semantic operations, but also other language (e.g., syntax, phonology) and cognitive operations (e.g., attention, cognitive control). The current findings show that the language-relevant network extends beyond the classical left perisylvian cortices and spans bilateral cortical, bilateral subcortical (bilateral thalamus, bilateral basal ganglia) and right cerebellar regions.

Incidence and Pathological Patterns of Nephrotic Syndrome among Infants and Children: A Systematic Review.

Nephrotic syndrome (NS) is known to be a prevalent chronic illness in young patients. Periorbital swelling in children with this condition is a recurring symptom, either with or without generalized edema.The current study aimedto examine the incidence and pattern of nephrotic syndrome in infants and children by thoroughly examining the recently available literature. A thorough search of PubMed, SCOPUS, Web of Science, Science Direct, and Google Scholar was conducted, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model, to find pertinent material. The Rayyan software (Qatar Computing Research Institute, Ar-Rayyan, Qatar) was utilized during the whole process. Data from a total of 1418 patients from nine trials were considered in this study. Numerous factors influenced the incidence, mean age, sex dominance, and histological patterns in various sample groups. The current findings conclude that variations in socioeconomic, regional, and genetic factors influence the development and pattern of these diseases. The prevalence of pediatric renal disorders differs throughout countries. Season of occurrence, response to corticosteroid treatment, and histopathologic findings appear to differ amongst the diagnosed cases.

Global meta-analysis reveals overall higher nocturnal than diurnal activity in insect communities

Insects sustain key ecosystem functions, but how their activity varies across the day–night cycle and the underlying drivers are poorly understood. Although entomologists generally expect that more insects are active at night, this notion has not been tested with empirical data at the global scale. Here, we assemble 331 quantitative comparisons of the abundances of insects between day and night periods from 78 studies worldwide and use multi-level meta-analytical models to show that insect activity is on average 31.4% (CI: −6.3%–84.3%) higher at night than in the day. We reveal diel preferences of major insect taxa, and observe higher nocturnal activity in aquatic taxa than in terrestrial ones, as well as in warmer environments. In a separate analysis of the small subset of studies quantifying diel patterns in taxonomic richness (31 comparisons from 13 studies), we detect preliminary evidence of higher nocturnal richness in tropical than temperate communities. The higher overall (but variable) nocturnal activity in insect communities underscores the need to address threats such as light pollution and climate warming that may disproportionately impact nocturnal insects.

Evaluation of Social Interventions with People with Disabilities: A Systematic Literature Review

Abstract This article aims to review the scientific production on social interventions (SI) in the field of persons with disabilities (PWD) and their families and to analyze its evaluations. To do so, it starts from the context of the social model of care of the United Nation’s Convention on the Rights of Persons with Disabilities and the sustainable development goals, and the evaluation of SI. The methodology proposes a systematic review of the existing literature on SI with PWD and their evaluation, based on the preferred reporting items for systematic review and meta-analysis (or PRISMA) model, including 19 articles. The results highlight issues such as the scarcity of publications with evaluations, the lack of homogeneity in the evaluation indicators used, the large number of interventions related to intellectual disability, and a large proportion of community interventions. This scoping review assists future research to consider different questions about evaluation indicators and implementation of the social model or social inclusion, among others.

Parameters That Can Be Used to Quantify Reduction Accuracy in Talar Neck Fractures and Malunions: A PRISMA-Compliant Scoping Review and Meta-Analysis.

Understanding the three-dimensional anatomy of the talar neck is essential in assessing the accuracy of reduction in talar neck fractures as well as for planning surgical correction for talar malunions. However, the geometrical parameters that describe this anatomy are sparsely reported in the orthopedics literature. We aimed to identify from the existing literature, geometrical parameters that describe the anatomy of the talar neck, determine how these are measured, and their normative values. A scoping literature review was conducted in accordance with thePreferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)extension for scoping reviews (PRISMA-ScR) guidelines. The primary searches were conducted on the PubMed, Embase, and Scopus databases. Any original research study looking at the human talus neck geometry was included. Parameters that described the anatomy of the talar neck were identified, andpooled estimates were determined by the random-effects meta-analysis model. Heterogeneity was assessed by the I2 test and leave-one-out meta-analysis. Subgroup analysis was done to compare the values of parameters between the Asian and Non-Asian populations. The risk of bias was assessed by the National Institutes of Health (NIH) Case Series Tool. The combined searches yielded 6326 results, of which 21 studies were included in the review and 15 in six different sets of metanalysis. The majority of the studies (n=19, 90.5%) evaluated adult tali, and only two (9.5%) evaluated pediatric tali.In most of the studies (n=13, 61.9%), talus neck geometry was evaluated on dry bones or anatomical specimens; evaluation by imaging techniques (radiographs, CT, MRI, and radiostereometric analysis) was used in eight studies, (39.1%). A total of eight different geometrical parameters (neck length, height, width, declination angle, inclination angle, torsion angle, circumference, and cross-sectional area) were identified. Except for talar torsion, variability was noted in methods of measurement of all other parameters. Subgroup analysis revealed that Asians had a higher neck height as compared to non-Asians; other parameters were not significantly different. Although the literature reports geometrical parameters to assess the talar geometry, the methods of measurement of these parameters are variable. Most of the available literature describes measurement techniques on cadaveric tali, and there is no literature on how these parameters should be measured on conventional CT or MRI slices. Further research needs to focus on the standardization of measurement techniques for these parameters on conventional CT and/or MRI scans.

Global and regional seroprevalence of coxiellosis in small ruminants: A systematic review and meta-analysis.

Coxiellosis is a neglected zoonosis for occupationally exposed people in many parts of the world. Sheep and goats are two important small ruminants that act as reservoirs for human contamination; however, there is a lack of comprehensive data on the epidemiological aspects of coxiellosis in sheep and goats at regional and global levels. The aim of this study was to systematically review the available articles on seroprevalence of coxiellosis in sheep and goats and estimate the overall seroprevalence in different regions. A systematic search strategy was performed in five electronic repositories for articles published until December 2021. Relevant data were extracted from the selected articles based on the inclusion criteria. A random effect meta-analysis model was used to analyse the data. Results are presented as the prevalence of seropositivity as a percentage and 95% confidence intervals. The global pooled seroprevalence of coxiellosis in sheep was 17.38% (95% confidence interval [CI]: 15.59%-19.17%). Overall, the regional level pooled prevalence estimates in sheep ranged from 15.04% (95% CI: 7.68%-22.40%) to 19.14% (95% CI: 15.51%-22.77%), depending on region. The global pooled seroprevalence of coxiellosis in goats was 22.60% (95% CI: 19.54%-25.66%). Overall, the regional level pooled prevalence estimates in goats ranged from 6.33% (95% CI: 2.96%-9.71%) to 55.13% (95% CI: 49.61%-60.65%), depending on the region. The prevalence estimates also varied significantly in both sheep and goats depending on age, sex, and rearing systems of the animals (p<0.001). Seroprevalence of coxiellosis in both sheep and goats is considerable. Routine monitoring of the sheep and goat populations is needed to prevent spillover infection in other livestock and humans.

Efficacy and safety of tyrosine kinase inhibitors for advanced metastatic thyroid cancer: A systematic review and network meta-analysis of randomized controlled trials.

Tyrosine kinase inhibitors (TKIs) have been approved for treating patients with clinically advanced metastatic thyroid cancer. However among the many TKIs, it remains unknown which regimen is the best choice for these patients. We conducted a systematic review and network meta-analysis to compare the survival benefits and efficacy of the available first-line regimens. We conducted an active search for phase II, III, or IV randomized controlled trials (RCTs) in the PubMed, Embase, and Cochrane databases to compare the effects of at least 2 drugs in the systemic treatment of advanced or metastatic thyroid cancer up to May 2023. The network meta-analysis model was adjusted using Bayesian Network model. Twelve trials with 2535 patients were included in our meta-analysis. The overall survival (OS), progression-free survival (PFS), and serious adverse events (SAEs) were taken as reference indicators. We also performed subgroup analyses of OS and PFS in medullary thyroid cancer (MTC) and radioiodine-refractory differentiated thyroid cancer (RR-DTC) to explore the variations of TKIs in different groups. As a result, apatinib had the best effect on overall survival (OS) (hazards ratio [HR] = 0.42, 95% confidence interval [CI] = 0.18-0.98), lenvatinib 18 mg/d has the best effect on progression-free survival (PFS) (HR = 0.13, 95% CI = 0.064-0.27), and cabozantinib 60 mg/d has the best safety profile. Our network meta-analysis showed that we believe that cabozantinib has the potential to become a widely used drug in clinical practice.

Robotic-assisted laparoscopic versus abdominal and laparoscopic myomectomy: A systematic review and meta-analysis.

Myomectomy is the preferred treatment for women with uterine fibroids and fertility requirements. There are three modalities are used in clinical practice for myomectomy: abdominal myomectomy (AM), laparoscopic myomectomy (LM), and robot-assisted laparoscopic myomectomy (RLM). To compare the perioperative and postoperative outcomes of RLM, AM, and LM. We searched PubMed, Web of Science, Embase, and Clinical Trials for relevant literature published between January 2000 and January 2023. We included all studies reporting peri- and postoperative outcomes of myomectomy in patients with uterine myomas. Surgical treatments were classified as RLM, LM, or AM. Two or more authors selected studies independently, assessed risk of bias, and extracted data. We derived mean difference (MD) or odds ratio (OR) with 95% confidence intervals (CIs) for each outcome, subgrouping trials by the patient characteristics and myoma characteristics. We used the I2 statistic to quantify heterogeneity and the random-effects model for meta-analysis when appropriate. We used the funnel plot to assess the publication bias. A total of 32 studies with 6357 patients were included, of which 1982 women had undergone RLM. The operating time was significantly longer (MD = 43.58, 95% confidence interval [CI]: 25.22-61.93, P < 0.001), and the incidence of cesarean section after myomectomy was significantly lower (OR = 0.27, 95% CI: 0.10-0.78, P = 0.02) in RLM than in LM. Compared with AM, the operation time, blood loss, blood transfusion rate, complication rate, total cost, length of hospital stay, and pregnancy rate of patients with RLM were significantly different. The safety and effectiveness of RLM are superior to those of AM but inferior to those of LM.
