Summary estimates of treatment effect from random effects meta-analysis give only the average effect across all studies. Inclusion of prediction intervals, which estimate the likely effect in an individual setting, could make it easier to apply the results to clinical practice 
RESEARCH METHODS & REPORTING
TLDR
How to determine whether data from existing trials are conclusive and, if not, whether a further trial is justified is considered. Expand
When is a further clinical trial justified?
TLDR
How to determine whether data from existing trials are conclusive and, if not, whether a further trial is justified is considered. Expand
Appraising Between-Study Homogeneity, Small-Study Effects, Moderators, and Confounders
Meta-analysis is the statistical synthesis of results from two or more clinical studies that address the same issue and compare two different interventions. Although the combination of results ofExpand
A comparison of the statistical performance of different meta-analysis models for the synthesis of subgroup effects from randomized clinical trials
TLDR
The results indicate that IPD models that allow for the between-trial variation in interaction effects should be given preference whenever investigating subgroup effects within a meta-analysis. Expand
Methods to calculate uncertainty in the estimated overall effect size from a random-effects meta-analysis.
TLDR
This paper aims to provide a comprehensive overview of available methods for calculating point estimates, confidence intervals, and prediction intervals for the overall effect size under the random-effects model, and indicates whether some methods are preferable than others by considering the results of comparative simulation and real-life data studies.

Getting more out of meta-analyses: a new approach to meta-analysis in light of unexplained heterogeneity.
TLDR
Analysing the distribution of an intervention-effect in random-effects models may enable clinicians to improve their understanding of the probability of particular-intervention effects in a new population. Expand
USING PREDICTION INTERVALS FROM RANDOM-EFFECTS META-ANALYSES IN AN ECONOMIC MODEL
TLDR
In meta-analyses with significant heterogeneity, the use of prediction intervals will produce wider ranges of treatment effect, and hence result in greater uncertainty, but a better reflection of the effect of the technology. Expand

TLDR
This study developed an elicitation method using external information on the "range" of treatment effects to infer the prior distribution for the between-study SD in a Bayesian random effects meta-analysis model to genuinely represent heterogeneity when data are sparse. Expand
Random effects meta‐analysis: Coverage performance of 95% confidence and prediction intervals following REML estimation
TLDR
Researchers should be cautious in deriving 95% prediction intervals following a frequentist random‐effects meta‐analysis until a more reliable solution is identified, especially when there are few studies. Expand
Performance of Between-study Heterogeneity Measures in the Cochrane Library
TLDR
Alternative heterogeneity measures, the and have strong agreement with the I2, while they are more robust than theI2 when outlying studies appear, and are applied to 20,599 meta-analyses in the Cochrane Library. Expand

Meta-analysis of individual participant data: rationale, conduct, and reporting
TLDR
The rationale for an individual participant data meta-analysis is described, how to conduct this type of study is outlined and how to interpret the data is outlined. Expand

TLDR
The authors’ analysis suggests that the mean treatment effect from a random-effects meta-analysis will only seldom be an appropriate representation of the efficacy expected in a future implementation, and modelers should consider either the predictive distribution of a future treatment effect or the future implementation itself.

Methods for Meta-Analysis in Medical Research
TLDR
This book discusses meta-analysis's development and uses, and discusses Bayesian methods in Meta-analysis, as well as specific and developing areas of applications inMeta-Analysis. Expand
Measuring inconsistency in meta-analyses
TLDR
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. Expand
Systematic Review: Why sources of heterogeneity in meta-analysis should be investigated
TLDR
This paper distinguishes between the concepts of clinical and statistical heterogeneity and exemplifies the importance of investigating heterogeneity by using published meta-analyses of epidemiological studies of serum cholesterol concentration and clinical trials of its reduction. Expand
A re-evaluation of random-effects meta-analysis
TLDR
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. Expand
How should meta-regression analyses be undertaken and interpreted?
TLDR
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. Expand
Meta-analysis: Potentials and promise
TLDR
The potentials and promise of meta-analysis of randomised controlled trials and various extensions beyond the calculation of a combined estimate are examined. Expand
Statistical heterogeneity in systematic reviews of clinical trials: a critical appraisal of guidelines and practice
TLDR
Recommendations that address practical issues are required to reduce the risk of spurious findings from investigations of heterogeneity, rather than simply adopting a cautious approach to their interpretation, unless a large number of studies is available. Expand
Bivariate analysis of sensitivity and specificity produces informative summary measures in diagnostic reviews.
TLDR
The bivariate model can be seen as an improvement and extension of the traditional sROC approach by reanalyzing the data of a published meta-analysis of diagnostic studies reporting pairs of sensitivity and specificity. Expand
