The conclusiveness of trial sequential analysis varies with estimation of between-study variance: a case study.
Kang Enoch, Hodges James S, Chuang Yu-Chieh, +3 more·BMC medical research methodology
BACKGROUND: Trial sequential methods have been introduced to address issues related to increased likelihood of incorrectly rejecting the null hypothesis in meta-analyses due to repeated significance testing. Between-study variance (τ) and its estimate () play a crucial role in both meta-analysis and trial sequent…

An evaluation of computational methods for aggregate data meta-analyses of diagnostic test accuracy studies.
Zhao Yixin, Khan Bilal, Negeri Zelalem F·BMC medical research methodology
BACKGROUND: A Generalized Linear Mixed Model (GLMM) is recommended to meta-analyze diagnostic test accuracy studies (DTAs) based on aggregate or individual participant data. Since a GLMM does not have a closed-form likelihood function or parameter solutions, computational methods are conventionally used to approximate…

Association between sedentary behavior and Brain-Derived Neurotrophic Factor (BDNF) in children and adolescents: A protocol for systematic review and meta-analysis.
de Oliveira Segundo Victor Hugo, de Azevedo Kesley Pablo Morais, de Medeiros Gidyenne Christine Bandeira Silva, +2 more·PloS one
BACKGROUND: There is evidence in the literature suggesting that high time spent in sedentary behavior (SB) can reduce the Brain-Derived Neurotrophic Factor (BDNF) levels, an important neurotrophin that plays a role in modulating cognition, learning and memory. Children and adolescents usually spend many hours a day on…

Agreement was moderate between data-based and opinion-based assessments of biases affecting randomized trials within meta-analyses.
Turner Rebecca M, Rhodes Kirsty M, Jones Hayley E, +10 more·Journal of clinical epidemiology
BACKGROUND AND OBJECTIVE: Randomized trials included in meta-analyses are often affected by bias caused by methodological flaws or limitations, but the degree of bias is unknown. Two proposed methods adjust the trial results for bias using empirical evidence from published meta-epidemiological studies or expert opinion…

Discovering the shared biology of cognitive traits determined by genetic overlap.
Guimaraes J P O F T, Bralten J, Greven C U, +3 more·NeuroImage
Investigating the contribution of biology to human cognition has assumed a bottom-up causal cascade where genes influence brain systems that activate, communicate, and ultimately drive behavior. Yet few studies have directly tested whether cognitive traits with overlapping genetic underpinnings also rely on overlapping…

A simplification and implementation of random-effects meta-analyses based on the exact distribution of Cochran's Q.

BACKGROUND: The random-effects (RE) model is the standard choice for meta-analysis in the presence of heterogeneity, and the standard RE method is the DerSimonian and Laird (DSL) approach, where the degree of heterogeneity is estimated using a moment-estimator. The DSL approach does not take into account the variabilit…
