Interpretation of random effects meta-analyses.
TLDR
Summary estimates of treatment effect from random effects meta-analysis give only the average effect across all studies, but inclusion of prediction intervals, which estimate the likely effect in an individual setting, could make it easier to apply the results to clinical practice.Abstract:

Measuring inconsistency in meta-analyses
TL;DR: A new quantity is developed, I 2, which the authors believe gives a better measure of the consistency between trials in a meta-analysis, which is susceptible to the number of trials included in the meta- analysis.

How should meta-regression analyses be undertaken and interpreted?
TL;DR: The examples considered in this paper show the tension between the scientific rationale for using meta-regression and the difficult interpretative problems to which such analyses are prone.

A re-evaluation of random-effects meta-analysis
TL;DR: It is suggested that random-effects meta-analyses as currently conducted often fail to provide the key results, and the extent to which distribution-free, classical and Bayesian approaches can provide satisfactory methods is investigated.
