Virtual Reality Distraction for Needle-Related Pain and Distress in Children: A Multicenter Randomized Controlled Trial.

This international multicenter randomized controlled trial aimed to compare the effectiveness of virtual reality (VR) distraction with an identical non-VR game in reducing needle-related pain and anxiety in children undergoing venous blood draw. The study involved 304 children aged 5-9 years undergoing a blood draw procedure, randomly allocated to one of three groups: VR distraction, non-VR distraction, and control group (usual care). The distraction task was based on the Multiple Object Tracking (MOT) paradigm, and the game was identical in design and gameplay for both VR and non-VR distraction groups. The primary outcome was self-reported pain intensity using the Faces Pain Scale-Revised (FPS-R). Secondary outcomes included child distress, attention/distraction to the blood draw, and parent and medical staff satisfaction with procedure. Analyses were conducted using analysis of variance and multivariable linear regression models. The results showed that VR distraction and non-VR distraction performed similarly, showing large effect sizes compared with standard care. There was no significant difference between the two types of distraction. The study's findings suggest that VR and non-VR distraction are similarly effective in reducing needle-related pain and anxiety in children undergoing venous blood draw. This is the first well-powered study comparing modern VR distraction with an identical task displayed on a smartphone or monitor screen. The study's results have important implications for using VR in clinical settings and suggest that investing in expensive VR equipment for acute pain management may not be necessary. The study protocol was pre-registered on Open Science Framework at https://osf.io/frsyc.

Effects of Conflict Management Strategies on Employees’ Performance in the University of Calabar Teaching Hospital, Calabar, Nigeria

This study evaluated the effects of conflict management strategies on employees’ performance in the University of Calabar Teaching Hospital, Calabar. The study employed survey research design in order to utilize a structured questionnaire in the collection of data for analysis. The population for the study was five hundred and fifty (550). The sample size for the study was two hundred and twenty six (226) using Krejcie and Morgan table of 1970. The hypothesis was tested and analyzed using a simple linear regression analysis model applying a statistical package for social sciences (SPSS) version 23. The study found that there are positive effects of conflict avoidance strategy on employees’ performance of the University of Calabar Teaching Hospital, Calabar. There is a significant effect of conflict collaboration strategy on employees’ commitment to goals achievement. There is a significant relationship between conflict accommodation strategy and employees’ motivation. There is also a significant conflict mediation strategy on employees’ involvement in the University of Calabar Teaching Hospital, Calabar. Based on the findings, the study recommended that management of organizations or institutions should monitor and intervene on issues that can lead to conflicts in order to enhance employees’ performance by adopting avoidance strategies. Management should employ a collaboration strategy or approach of win-win method of conflict resolution in order to enhance employees’ commitment. Management should also attend to conflicting situations as urgently as possible in order to avoid those factors that can hinder employees’ motivation and commitment to goal achievement. Management should also use a mediator in resolving conflicts on a continuous basis.

Concentrations and influencing factors of 17 elements in placenta, cord blood, and maternal blood of women from an e-waste recycling area

BackgroundThe effects of prenatal element exposure on mothers and fetuses have generated concern. Profiles of trace and toxic elements in biological material are urgently desired, especially for women who reside near e-waste recycling facilities. The aim of this study was to investigate elements concentrations in placenta, cord blood, and maternal blood of women and to evaluate the influencing factors. MethodsA group of 48 women from an e-waste recycling site and a group of 31 women from a non-e-waste recycling site were recruited. Basic characteristics were collected by questionnaire and the concentrations of 17 elements in placenta, cord blood, and maternal blood samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). Finally, the generalized linear model regression analysis (GLM) was used to test the association between element concentrations and possible factors. ResultsCompared to the control group, the exposed group had significantly elevated cadmium (Cd), zinc (Zn), nickel (Ni), and antimony (Sb) in placenta, and higher lead (Pb) in maternal blood and cord blood (P<0.05). Sb concentration in maternal blood was significantly lower than in the control group (P<0.05). GLM analysis showed that element concentrations were mainly associated with maternal age [chromium (Cr), iron (Fe), selenium (Se), cobalt (Co), mercury (Hg) in placenta, copper (Cu) in maternal blood], education (Se, Sb in placenta), family income (Cu in maternal blood and Ni in placenta), passive smoking [Cu and Zn in placenta, Pb in maternal blood], and e-waste contact history (Hg in cord blood, Cu, Zn, and Cd in maternal blood). ConclusionsWomen in the e-waste recycling area had higher toxic element levels in the placenta and blood samples. More preventive measures were needed to reduce the risk of element exposure for mothers and fetuses in these areas.

Computed Tomography and Dual-Energy X-Ray Asorptiometry body composition parameter harmonisation to universalise adipose tissue measurements in a population-based cross-sectional study.

To harmonise computed tomography (CT) and dual-energy x-ray absorptiometry (DXA) body composition measurements allowing easy conversion in longitudinal assessments and across cohorts to assess cardiometabolic risk and disease. Retrospective cross-sectional observational study from 1996 to 2008 included participants in the Pennington Center Longitudinal Study (PCLS) (N = 1967; 571 African American/1396 White). Anthropometrics, whole-body DXA and abdominal CT images were obtained. Multi-layer segmentation techniques (Analyze; Rochester, MN) quantified visceral adipose tissue (VAT). Clinical biomarkers were obtained from routine blood samples. Linear models were used to predict CT-VAT from DXA-VAT and examine the effects of traditional biomarkers on cross-sectional-VAT. Predicted CT-VAT was highly associated with measured CT-VAT using ordinary least square linear regression analysis and random forest models (R2 = 0.84; 0.94, respectively, p < .0001). Model stratification effects showed low variability between races and sexes. Overall, associations between measured CT-VAT and DXA-predicted CT-VAT were good (R2 > 0.7) or excellent (R2 > 0.8) and improved for all stratification groups except African American men using random forest models. The clinical effects on measured CT-VAT and DXA-VAT showed no significant clinical difference in the measured adipose tissue areas (mean difference = 0.22 cm2). Random forest modelling seamlessly predicts CT-VAT from measured DXA-VAT to a degree of accuracy that falls within the bounds of universally accepted standard error.

Prediction of Bioethanol from Production of Lignocellulosic Biomass Waste from Agriculture and Livestock Using Regression Analysis Model

Background Every year, the food supply must need to increase to accommodate population growth and food consumption increases. It causes the production of lignocellulosic biomass waste (LBW) in Indonesia from sector of agriculture and livestock also increase. Contrast to energy supply, energy demand increases but energy supply from fossil fuel become limit. More than 80% of LBW is dumped or burned, whereas the LBW has the potential as raw material of sustainable bioenergy, especially bioethanol to replace or mix with fossil fuel. This study aimed to predict the bioethanol production from potential of LBW to optimize its utilization. Potential of LBW production is estimated based on production of LBW lignocellulose component (cellulose, hemicellulose, and lignin). The novelty of this study is obtained predicted values for bioethanol production based on LBW production using a regression analysis model. Methods The data of LBW production is calculated based on converting waste of the crops production (for agriculture sector) and animal unit (AU) (for livestock sector). The data of LBW consist of rice straw, corn stover, sugarcane bagasse, cassava peel, paunch content, and feces. This study use linear regression analysis model to predict bioethanol production from LBW. Results Estimation average LBW lignocellulose production in Indonesia is around 104.47 million tons, and can produce around 59.98 billion gallons (227.01 billion liters) of bioethanol. The regression model based on lignocellulose production (R2) was 0.9925 (cellulose), 0.9848 (hemicellulose), and 0.9294 (lignin). Production of LBW in Indonesia is highest in Southeast Asia and has increased 2.07% per year because crops production, ruminant population, and ruminants slaughtered increase. This value will continue to increase, same with bioethanol production from LBW production. Conclusions Overall, Indonesia has potential to produce bioethanol from LBW. Using the entire the LBW for bioethanol make it possible to meet domestic energy demands in a sustainable.

The Effect of Return On Equity and Current Ratio on Firm Value with Capital Structure as an Intervening Variable in Food And Beverage Sub-Sector Companies Listed on the Indonesia Stock Exchange for the Period 2017-2021

A growing number of people are showing an interest in investing for the long haul by putting their money into the capital markets. The food and beverage industry is one of these that industry 4.0 has identified as a priority. With more and more companies joining the Indonesia Stock Exchange, it's getting harder for companies to stand out and attract investors by raising their company value. For the years 2017–2021, this research set out to examine the relationship between firm value, return on equity, current ratio, and capital structure among food and beverage companies traded on the Indonesia Stock Exchange. This study's sample was determined using a purposive sampling strategy utilising data from 10 different companies. The secondary data used in this study was sourced from the Indonesia Stock Exchange's website (www.idx.co.id) as well as from connected companies' official websites. The data is analysed using SPSS 25 software and a multiple linear regression analysis model, as well as path analysis. The findings indicate that Capital Structure is significantly impacted to a lesser extent by Return On Equity and Current Ratio. Firm Value is somewhat affected by Return On Equity, although it is unaffected by Current Ratio and Capital Structure. Return On Equity (ROE) has no mediating influence on business value via capital structure. In contrast, capital structure acts as an intervening variable in the current ratio, which has an indirect impact on firm value

Stock Price Synchronicity And Institutional Ownership: The Role Of Sustainability Reporting, Political Connection, And Leverage

This research study is aimed to evaluate how institutional ownership affects the degree of correlation among stock prices, as well as the influence of sustainability reporting, political connections, and leverage. The study takes sample data from companies that were on the LQ45 index at the end of the year, or December 31, for the years 2019–2022 using purposive sampling method. Hypothesis testing uses a multiple linear regression analysis model in the form of a moderated regression analysis (MRA) to test moderator variables. The findings indicated that leverage has negative effect on stock price synchronicity, while neither sustainability reporting nor political connections influenced stock price synchronicity. Institutional ownership as a moderating variable is able to strengthen the negative influence of leverage on stock price synchronicity, On the other hand, the presence of institutional ownership does not have an ability to impact the correlation between sustainability reporting and political relationships on stock price synchronicity

Reproductive outcomes of dual trigger therapy with GnRH agonist and hCG versus hCG trigger in women with diminished ovarian reserve: a retrospective study

BackgroundDiminished ovarian reserve (DOR) is one of the obstacles affecting the reproductive outcomes of patients receiving assisted reproductive therapy. The purpose of this study was to investigate whether dual trigger, including gonadotropin‐releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG), can improve pregnancy outcomes in patients with DOR undergoing in vitro fertilization (IVF) cycles using mild stimulation protocols.MethodsA total of 734 patients with DOR were included in this retrospective study. Patients were divided into a recombinant hCG trigger group and a dual trigger group (hCG combined with GnRHa) according to the different trigger drugs used. The main outcome measures included the number of oocytes retrieved, the fertilization rate, the number of transferable embryos, the implantation rate, the clinical pregnancy rate, the miscarriage rate, the live birth rate (LBR), and the cumulative live birth rate (CLBR). Generalized linear model and logistic regression analyses were performed for confounding factors.ResultsThere were 337 cycles with a single hCG trigger and 397 cycles with dual trigger. The dual trigger group demonstrated significantly higher numbers of retrieved oocytes [3.60 vs. 2.39, adjusted β = 0.538 (0.221–0.855)], fertilized oocytes [2.55 vs. 1.94, adjusted β = 0.277 (0.031–0.523)] and transferable embryos [1.22 vs. 0.95, adjusted β = 0.162 (-0.005–0.329)] than did the hCG trigger group, whereas no significant difference in the fertilization rate was observed between the two groups. Moreover, the embryo transfer cancellation rate (35.5% vs. 43.9%) was obviously lower in the dual trigger group. Among the fresh embryo transfer cycles, the implantation rate, clinical pregnancy rate, miscarriage rate and live birth rate were similar between the two groups. After controlling for potential confounding variables, the trigger method was identified as an independent factor affecting the number of oocytes retrieved but had no significant impact on the CLBR.ConclusionsDual triggering of final oocyte maturation with hCG combined with GnRHa can significantly increase the number of oocytes retrieved in patients with DOR but has no improvement effect on the implantation rate, clinical pregnancy rate or LBR of fresh cycles or on the CLBR.

Assessing right ventricular peak strain in myocardial infarction patients with mitral regurgitation by cardiac magnetic resonance feature tracking.

Although it is known that mitral regurgitation (MR) in patients with myocardial infarction (MI) may increase the right ventricular (RV) afterload, leading to RV dysfunction, the exact detrimental effects on RV function and myocardial peak strain remain unresolved. In this study, we assessed the impact of MR on the impairment of RV myocardial deformation in patients with MI and explored the independent influential factors of RV peak strain. A total of 199 MI participants without or with MR were retrospectively assessed in this study. The cardiovascular magnetic resonance examination protocol included a late gadolinium-enhanced (LGE) imaging technique and a cine-balanced steady-state free precession sequence. Statistical tests, including two independent sample t-test or Mann-Whitney U-test, analysis of variance, Kruskal-Wallis test, and multiple linear regression analysis models were performed. The MI (MR+) group exhibited significantly lower RV strain parameters in the radial, circumferential and longitudinal directions when compared to the control and the MI (MR-) groups (both P<0.05). The RV global longitudinal peak strain (GLPS) in the MI group significantly decreased when compared with that in the control group (P<0.05). As moderate-severe MR worsened in patients with MI, RV myocardial global peak strain and the peak systolic strain rate (PSSR) gradually decreased. Multiple linear regression analysis revealed that left ventricular (LV) GLPS, triglycerides, and age were independently correlated with RV GLPS (all P<0.05). RV end-systolic volume (RVESV) acted as an independent association factor for RV global peak strain. MR may exacerbate the impairment of RV peak strain and functions in patients with MI. LV GLPS was positively correlated with RV GLPS. However, RVESV, triglycerides, and age acted as independent risk factors associated with worsening RV GLPS.

Pengaruh Opini, Reputasi KAP, COSO Framework, Laba, dan Struktur Modal terhadap Tingkat Kepercayaan Investor

This research aims to determine the effect of audit opinion, reputation of public accountant firms, the implementation of COSO framework, net income, and capital structure on the level of investor confidence. In this study, multiple linear regression analysis model was used to determine the effect between independent variables on the level of investor confidence, besides that, descriptive statistical analysis, classical assumption test, partial effect test, simultaneous effect test, and coefficient of determination test will also be carried out. The level of investor confidence will be described by the stock price of a company. The share price will take a number from the closing price on December 31 of each year. There were 4 samples of companies from the infrastructure, utilities, and transportation sectors and data obtained from 2011 to 2021 tested in this study. The four companies are AirAsia Indonesia Tbk, Leyand International Tbk, Steady Safe Tbk, and Garuda Indonesia Tbk. The results of the study indicate that the audit opinion variable, the application of the COSO Framework, net income, and capital structure can not be proven to have a partial influence on the level of investor confidence. However, the variable reputation of public accountant firms has a partial influence on the level of investor confidence. For the four independent variables themselves have a simultaneous influence on the investor confidence. A high level of investor confidence is coveted by all companies. The higher the investor's trust, the higher capital that can be used by the company for operational activities. Every company is flocking to increase its value in order to gain strong investor confidence. The components studied are audit opinion, KAP reputation, COSO Framework, net income, and capital structure on the level of investor confidence in the infrastructure, utilities and transportation industries. In this study, multiple linear regression analysis model was used to determine the effect between independent variables on the level of investor confidence, besides that, descriptive statistical analysis, classical assumption test, partial effect test, simultaneous effect test, and coefficient of determination test will also be carried out. The level of investor confidence described by the stock price of a company. The share price will take a number from the closing price on December 31 of each year.

The results of the study indicate that the audit opinion variable, COSO Framework, net income, and capital structure can not be proven to have a partial influence on the level of investor confidence. However, the variable KAP reputation has a partial influence on the level of investor confidence. For the four independent variables themselves have simultaneous influence on the investor confidence.

Association of mixed polycyclic aromatic hydrocarbons exposure with oxidative stress in Korean adults

Polycyclic aromatic hydrocarbons (PAHs) are widespread pollutants associated with several adverse health effects and PAH-induced oxidative stress has been proposed as a potential mechanism. This study evaluated the associations of single and multiple PAHs exposure with oxidative stress within the Korean adult population, using serum gamma glutamyltransferase (GGT) as an oxidative stress marker. Data from the Second Korean National Environmental Health Survey (2012–2014) were analyzed. For analysis, 5225 individuals were included. PAH exposure was assessed with four urinary PAH metabolites: 1-hydroxyphenanthrene, 1-hydroxypyrene, 2-hydroxyfluorene, and 2-naphthol. After adjusting for age, sex, body mass index, drinking, passive smoking, and current smoking (model 1), as well as the presence of diabetes and hepatobiliary diseases (model 2), complex samples general linear model regression analyses for each metabolite revealed a significant positive association between Ln(1-hydroxyphenanthrene) and Ln(GGT) (model 1: β = 0.040, p < 0.01 and model 2: β = 0.044, p < 0.05). For the complete dataset (n = 4378), a significant positive association was observed between mixture of four urinary PAH metabolites and serum GGT in both the quantile g-computation and the Bayesian kernel machine regression analysis. Our study provides evidence for the association between mixed PAH exposure and oxidative stress.

Analysis of Hospitalization Costs and Influencing Factors of AKI in Adult Patients

Objective: To investigate the economic burden of patients with acute kidney injury (AKI) by analyzing the distribution of hospitalization expenses and its influencing factors in the Affiliated Hospital of Hebei University. Methods: The hospitalization information of patients with AKI from January 2020 to January 2023 was collected and sorted through the hospital charging system and the factors affecting the total hospitalization cost were analyzed by multiple linear regression. Results: Univariate analysis showed that age, occupation, marriage, length of hospitalization, recovery of renal function, and stage of AKI had significant effects on hospitalization cost (P &lt; 0.05). The result of the multiple linear regression analysis model showed that age (t = 4.11, P &lt; 0.0001), length of hospitalization (t = 16.10, P &lt; 0.0001), recovery of renal function (t = 3.26, P &lt; 0.0001), AKI stage (t = 5.23, P = 0.002) are factors affecting the economic burden of patients with AKI. Conclusion: AKI patients should be managed according to age stratification to effectively control the progression of the disease and improve the quality of the medical services provided. This will reduce the economic burden of patients.

It demonstrated positive effects on cost leadership and competitive advantage differentiation. However, an indirect negative impact on nonfinancial performance was observed through the influence on cost leadership, suggesting a trade-off between cost reduction and other nonfinancial factors.Conclusion: The study acknowledges limitations in sample size and the need for considering additional factors. Further research is required to understand Beyond Budgeting’s limited adoption in Iraq. The study contributes valuable insights on Beyond Budgeting as a substitute for traditional approaches, benefiting managers and policymakers.Contribution: This study emphasises Beyond Budgeting’s significant impact on Iraqi SME performance, highlighting the relationship between Beyond Budgeting, competitive advantage strategies, financial and nonfinancial performance. The findings provide insights for enhancing budgeting practices in Iraqi SMEs.

Burden of treatment and quality of life in relapsing remitting multiple sclerosis patients under early high efficacy therapy in Argentina: Data from the Argentinean registry

The objective of this study was to describe and compare the burden of treatment (BOT) and the quality of life (QoL) in early high efficacy therapy (HET) vs. escalation therapy in relapsing remitting multiple sclerosis (RRMS) patients included in RelevarEM, the Argentinean registry of MS (RelevarEM, NCT 03,375,177). Methodscross sectional study conducted between September and December 2022. Participating patients were adults, RRMS patients who initiated (during the last three years) their treatment with a HET (natalizumab, ocrelizumab, alemtuzumab, cladribine) or with escalation treatment (beta interferon, glatiramer acetate, teriflunomide, dimethyl fumarate or fingolimod). Clinical and demographic aspect were collected. QoL and BOT was measured with the validated to Spanish MusiQol and BOT questionnaire. Propensity score (PS)-based nearest-neighbor matching was applied to homogenize groups. Comparisons were be done using a linear regression analysis model stratified by matched pairs, with BOT and QoL assessments as main outcomes. Results269 patients were included in the analysis, mean age 33.7 ± 5.7 years, 193 (71.7 %) were female. A total of 136 patients were on early HET while 133 were on escalation therapy. In the entire group the mean total BOT score (±SD) was 48.5 ± 15.3 while in the group of patients receiving early HET we observed that the mean BOT score (±SD) was 43.5 ± 12.2 vs. 54.3 ± 13.3 in escalation treatment (p < 0.0001). Regarding the score QoL (±SD), in the entire sample we observed a global score of 77.4 ± 11.2. When we stratified groups, in HET (±SD) it was 81.3 ± 14 vs. 74.1 ± 18.3 in escalation therapy (p = 0.0003). Conclusionin this multicenter study that included 269 patients from Argentina we observed in early HET a significantly lower BOT and higher QoL than patients receiving escalation therapy.

Lipid parameters and depression in patients with chronic tinnitus: A cross-sectional observation

BackgroundPathophysiological theories assume importance of metabolic abnormalities in patients with major depression - and possibly chronic tinnitus. Although chronic tinnitus frequently correlates with depression, links between high-density lipoprotein (HDL) and depression are uninvestigated. MethodsTwo-hundred patients with chronic tinnitus (Mage = 55; 51% female) were examined. Serum levels of total cholesterol (TC), triglycerides (TGs), HDL, low-density lipoprotein cholesterol (LDL), non-HDL, as well as LDL/HDL and TC/HDL ratios were analysed. Questionnaires included depression subscales of the ICD-10 Symptom Rating, the Hospital Anxiety and Depression Scale (HADS_D), and the Berlin Mood Questionnaire (BSF). Multivariate analyses of covariance and linear regression models - which controlled age, tinnitus-related distress and perceived stress - investigated between-subgroup differences (p < 0.05) and linear associations between HDL indices and depression (p < 0.01). ResultsHDL levels did not differ for tinnitus-symptom durations, smoking and alcohol use levels, statin or antihypertensive drug use, and body-mass indices. Relative to non-to-mildly depressed patients with chronic tinnitus, patients with moderate-to-severe depression (n = 45; 23%) had significantly lower HDL levels (d = −0.35) and higher LDL/HDL (d = 0.39) and TC/HDL ratios (d = 0.40). Across participants, HDL-levels were negatively associated with depression as measured by the HADS_D and BSF_indifference scales. ConclusionsIn keeping with general depression research, low serum HDL levels correlate with depressive symptomatology in patients with chronic tinnitus. This association may be influenced by proximal (e.g. modulations of HPA-axis activity) or distal factors (e.g. maladaptive coping behaviours) – both of which should be conceptualized within psychological stimulus-processing frameworks.

In-Database Data Imputation

Missing data is a widespread problem in many domains, creating challenges in data analysis and decision making. Traditional techniques for dealing with missing data, such as excluding incomplete records or imputing simple estimates (e.g., mean), are computationally efficient but may introduce bias and disrupt variable relationships, leading to inaccurate analyses. Model-based imputation techniques offer a more robust solution that preserves the variability and relationships in the data, but they demand significantly more computation time, limiting their applicability to small datasets. This work enables efficient, high-quality, and scalable data imputation within a database system using the widely used MICE method. We adapt this method to exploit computation sharing and a ring abstraction for faster model training. To impute both continuous and categorical values, we develop techniques for in-database learning of stochastic linear regression and Gaussian discriminant analysis models. Our MICE implementations in PostgreSQL and DuckDB outperform alternative MICE implementations and model-based imputation techniques by up to two orders of magnitude in terms of computation time, while maintaining high imputation quality.

Applicability of the Cumberland Ankle Instability Tool in Elite Volleyball Athletes: A Cross-Sectional Observational Study.

The ease of administration of the Cumberland Ankle Instability Tool (CAIT) could represent a methodology for periodically evaluating athletes, preventing ankle instability injuries. This study aimed to achieve three objectives: (a) to evaluate the applicability of the CAIT scale in volleyball; (b) to explore whether ankle instability presents a greater risk in lower-level volleyball categories and whether elite athletes demonstrate an ability to mitigate this risk; and (c) to identify potential predictors of ankle instability. Eighty female volleyball players participated in this cross-sectional observational study. The CAIT was administered to evaluate the athletes belonging to some teams in Series A, B, and C. The Spearman's ranks correlation coefficient showed significant correlations between CAIT items. Additionally, the Cronbach's α showed a high internal consistency. Our results showed a significant difference between athletes who reported pain and those who did not (p < 0.001). The multiple linear regression model analysis showed that pain was a predictor of ankle instability (p < 0.001). Our findings suggest that the CAIT can be used to evaluate ankle stability in volleyball players. This scale could represent a valuable tool for implementing specific intervention programs to prevent ankle injuries in athletes.

GripAble: Interrater reliability and normative grip strength of UK population

BackgroundHand grip strength is an established indicator of individual health status and is used as a biomarker for predicting mortality, disability, and disease risks. GripAble hand grip dynamometer offers a modernized approach to measuring grip strength with its digital and high-accuracy measurement system. PurposeThis study aimed to (1) assess the interrater reliability of maximum grip strength (MGS) measurement and (2) establish GripAble’s own gender-, age group- and hand-stratified normative MGS reference values of the adult UK population. Study DesignCross-sectional study design. MethodsInterrater reliability among three raters assessing 30 participants across diverse age groups was measured using the intraclass correlation. In the second study, 11 investigators gathered MGS data from 907 participants across diverse age groups and gender. The average, standard deviation, minimum, median, maximum, and percentiles of MGS were computed for each gender, age group, and hand (L/R). The relationship between MGS and age was examined using quantile regression analysis. Additionally, generalized linear model regression analysis was conducted to explore the influence of participants' demographics (gender, hand [L/R], hand length, hand circumference, age, weight, and height) on MGS. ResultsMGS measurements between raters showed excellent agreement (ICC(2,1) = 0.991, 95% confidence interval [0.98, 1.0]). The MGS and age relationship follows a curvilinear pattern, reaching a peak median MGS values of up to 20 kg between 30 and 49 years for females and up to 35 kg between 30 and 59 years for males. Subsequently, MGS declined as age advanced. Gender and hand (L/R) emerged as the primary factors influencing MGS, followed by hand length, hand circumference, age, weight, and height. ConclusionsThe presented normative MGS reference values can be used for interpreting MGS measurements obtained from adults in the United Kingdom using GripAble. This study, along with previous studies on GripAble devices, confirms GripAble as a reliable and valid tool for measuring MGS.
