TLDR
In this paper, a method for combining results across independent-groups and repeated measures designs is described, and the conditions under which such an analysis is appropriate are discussed, and a meta-analysis procedure using design-specific estimates of sampling variance is described.Abstract:
When a meta-analysis on results from experimental studies is conducted, differences in the study design must be taken into consideration. A method for combining results across independent-groups and repeated measures designs is described, and the conditions under which such an analysis is appropriate are discussed. Combining results across designs requires that (a) all effect sizes be transformed into a common metric, (b) effect sizes from each design estimate the same treatment effect, and (c) meta-analysis procedures use design-specific estimates of sampling variance to reflect the precision of the effect size estimates.read more

Depression and sleep quality in older adults: a meta-analysis.
Nathália Brandolim Becker,Saul Neves de Jesus,Karine Alexandra Del Rio João,João Viseu,Rute Isabel Santos Martins +4 more
TL;DR: It is found that an older person’s lack of good sleep quality is significantly related with depression, and future research should consider the importance of additional variables (e.g. moderators) in order to understand and investigate viable interventions for prevention and health promotion in the elderly.

Insulin sensitivity following exercise interventions: systematic review and meta-analysis of outcomes among healthy adults

TL;DR: It is documented that exercise is a valuable primary care and community health strategy for healthy adults to improve insulin sensitivity and lower the risk for diabetes conferred by insulin resistance.

TL;DR: Yoga improved glycemic outcomes and other risk factors for complications in adults with T2DM relative to a control condition and was associated with significant improvements in lipid profile, blood pressure, body mass index, waist/hip ratio and cortisol levels.

Evaluating the mechanisms of change in motivational interviewing in the treatment of mental health problems: A review and meta-analysis.
Mia Romano,Lorna Peters +1 more
TL;DR: While MI did not increase patient motivation more so than did comparison conditions, MI showed a favourable effect on patient engagement variables, suggesting that patient engagement with treatment may be a potential mechanism of change in populations diagnosed with anxiety, mood, and psychotic disorders.

TL;DR: In this article, the authors present a model for estimating the effect size from a series of experiments using a fixed effect model and a general linear model, and combine these two models to estimate the effect magnitude.
