Network meta-analysis is becoming a common approach to combine direct and indirect comparisons of several treatment arms. In recent research, there have been various developments and extensions of the standard methodology. Simultaneously, cluster randomized trials are experiencing an increased popularity, especially in the field of health services…

Meta-analyses are often used to synthesize the findings of studies examining the correlational relationship between two continuous variables. When only dichotomous measurements are available for one of the two variables, the biserial correlation coefficient can be used to estimate the product-moment correlation between the two underlying…

Network meta-analysis has evolved into a core method for evidence synthesis in health care. In network meta-analysis, 3 or more treatments for a given medical condition are compared, based on a number of clinical studies, usually randomized controlled trials. Often, many different endpoints are investigated, related to different aspects of the…

Systematic reviews and meta-analyses are the cornerstones of evidence-based medicine and inform treatment, diagnosis, or prevention of individual patients as well as policy decisions in health care. Statistical methods for the meta-analysis of intervention studies are well established today. Meta-analysis for diagnostic accuracy trials has also…

Association of congenital cytomegalovirus (CMV) infection with autism spectral disorder (ASD) has been suggested since 1980s. Despite the observed association, its role as a risk factor for ASD remains to be defined. In the present review, we systematically evaluated the available evidence associating congenital CMV infection with ASD using…

Researchers analyzed that social emotional learning is one of the factors for effective learning to take place. Researchers call academic resilience as one of the important components of social emotional learning. It is the students' ability to compete and get success in environment where they face adverse conditions. These adverse conditions…

To investigate the factor structure of the Figural Torrance Tests of Creative Thinking (Figural TTCT), a meta-confirmatory factor analysis was performed. A sample of 33 correlation matrices from 26 studies (N[subscript individuals] = 6,982) was included in the meta-analysis. Four different factor models previously presented in the literature were…

Background: The topic of gender differences in mathematical performance has received considerable attention in the fields of education, sociology, economics and psychology. Aims: We analysed gender differences based on data from the Beijing Assessment of Educational Quality in China. Sample: A large data set of Grade 5 and Grade 8 students who…

Meta-analytic studies are syntheses of literature in which researchers use statistical means to summarize the findings presented across primary studies. They are of great interest in the fields of medicine and social sciences with numerous examples published in peer-reviewed journals. However, it appears that career and technical education (CTE)…

Although algebraic reasoning has been considered as an important factor influencing students' mathematical performance, many students struggle to build concrete algebraic reasoning. Metacognitive training has been regarded as one effective method to develop students' algebraic reasoning; however, there are no published meta-analyses that include…

Over the past decade, numerous studies have reported that infants prefer prosocial agents (those who provide help, comfort, or fairness in distributive actions) to antisocial agents (those who harm others or distribute goods unfairly). We meta-analyzed the results of published and unpublished studies on infants aged 4-32 months and estimated that…

To answer the call of introducing more Bayesian techniques to organizational research (e.g., Kruschke, Aguinis, & Joo, 2012; Zyphur & Oswald, 2013), we propose a Bayesian approach for meta-analysis with power prior in this article. The primary purpose of this method is to allow meta-analytic researchers to control the contribution of each…

Interfaith initiatives are seen as promising sites for societal change and personal transformation. However, many questions about the actual outcomes of such initiatives have remained unanswered. Therefore, a systematic review was conducted, focusing on 1) the outcomes of interfaith initiatives and 2) the methods used to evaluate these outcomes.…

Despite the growing body of research regarding the effectiveness of MALL (mobile-assisted language learning) technologies on foreign language (FL) learners' speaking skill development, a comprehensively quantitative meta-analysis regarding the effect sizes of these studies is still lacking. To solve the problem, this study reported results based…

Predictors of student academic success do not always replicate well across different learning designs, subject areas, or educational institutions. This suggests that characteristics of a particular discipline and learning design have to be carefully considered when creating predictive models in order to scale up learning analytics. This study…
