PurposeThe purpose of this study is to evaluate the effects of exercise therapy on neck pain (NP) levels, neck dysfunction, and quality of life in patients with nonspecific neck pain (NSNP), and to compare the differences between different exercise interventions, thereby providing evidence for the application of exerci…

BACKGROUND: Meta-analyses of clinical trial safety data have risen in importance beyond regulatory submissions. During drug development, sponsors need to recognize safety signals early and adjust the development program accordingly, so as to facilitate the assessment of causality. Once a product is marketed, sponsors a…

Zinc acexamate (ZAC) is a new drug for the treatment of peptic ulcer. The present study was performed in order to evaluate the clinical efficacy of ZAC in peptic ulcer, using a meta-analysis of all randomized clinical trials performed with this drug. Eighteen studies were reviewed, but only 13 were considered in the fi…

BACKGROUND/OBJECTIVES: In systematic reviews (SRs) with a meta-analysis, a subgroup analysis can be utilised to explore heterogeneity of treatment effects across patient characteristics and assess how patient characteristics, types of intervention, or trial characteristics modify the treatment effect. The aim of this m…

BACKGROUND: Acne is a common skin condition that can cause permanent scarring and profoundly affect patients' quality of life. Despite the increasing diversity of acne scar treatments, there is a dearth of comprehensive evidence-based guidelines to help clinicians and patients make the best choices. This study aimed to…

Meta-analysis (eight general population longitudinal studies) describes the relationships (regressions) between quantity per occasion and depressive symptomatology over time. Quantity and depression are the strongest and most consistent predictors of final levels of themselves in all data sets. Age significantly and co…

Prominent nonquantitative reviews of research evaluating school-based interventions designed to deter adolescents from the use of tobacco, alcohol and other drugs found the methodology to be flawed and thus little evidence existed that the interventions had the desired impact. Recent meta-analytic reviews indicate that…

BACKGROUND: Since the COVID-19 outbreak, preliminary research has shown that some risk-associated conditions increase death and severe complications of the disease, hypertension being one of them. Thus, numerous meta-analyses have been conducted to explore this issue. Therefore, this umbrella review aims to perform a m…

Applications of meta-analysis have begun to appear with some regularity in the dental research literature. Recently, a meta-analysis played a high-profile role in the ongoing academic debate concerning the relative anticaries efficacy of dentifrices containing fluoride as sodium fluoride and as sodium monofluorophospha…

This meta-analysis demonstrated that interventions have a significant (p less than .05) immediate posttreatment influence on elders' subjective well-being but that their beneficial effect dissipates within 1 month. For 28 effect sizes derived from immediate posttreatment occasions (delay = 0 days), the median value was…

Evidence for an independent role of increased physical activity in the primary prevention of coronary heart disease has grown in recent years. The authors apply the techniques of meta-analysis to data extracted from the published literature by Powell et al. (Ann Rev Public Health 1987;8:253-87), as well as more recent…

Many randomized trials evaluate an intervention effect on time-to-event outcomes. Individual participant data (IPD) from such trials can be obtained and combined in a so-called IPD meta-analysis (IPD-MA), to summarize the overall intervention effect. We performed a narrative literature review to provide an overview of…

Many pharmacologic regimens have been recommended as supplemental treatment strategies for cocaine abuse. Using the technique of meta-analysis, we compared and combined the data from six studies to examine the efficacy of desipramine as an adjunctive treatment approach for cocaine addiction. These studies were randomiz…

OBJECTIVES: Evaluating the variation in the strength of the effect across studies is a key feature of meta-analyses. This variability is reflected by measures like τ(2) or I(2), but their clinical interpretation is not straightforward. A prediction interval is less complicated: it presents the expected range of t…

It is aimed to evaluate the effectiveness and provide evidence-based medical support for acupuncture as a prophylactic treatment for migraines. Randomized controlled trials (RCTs) from inception to April 2022 are included in 14 databases. Pairwise meta-analysis is conducted using STATA software V14.0, while Windows Bay…
