  author={Jessica Gurevitch and Julia Koricheva and Shinichi Nakagawa and Gavin B. Stewart},
Meta-analysis is the quantitative, scientific synthesis of research results. Since the term and modern approaches to research synthesis were first introduced in the 1970s, meta-analysis has had a revolutionary effect in many scientific fields, helping to establish evidence-based practice and to resolve seemingly contradictory research outcomes. At the same time, its implementation has engendered criticism and controversy, in some cases general and others specific to particular disciplines. Here… 

The synthesis of scientific shreds of evidence: a critical appraisal on systematic review and meta-analysis methodology

Systematic reviews and meta-analyses, conducted by subsequent strict protocols to guarantee reproducibility and decrease bias, have become more common in the synthesis of evidence.

Meta-analyses that statistically synthesize evidence from multiple research studies can play an important role in advancing evidence-informed prevention science. When done in the context of a

The Application of Meta-Analysis in Econometric

Meta-analysis can enhance the statistical efficiency of data processing in academic research, effectively save the cost of scientific research and improve the strength of argumentation. To be able to

How to conduct a meta-analysis in eight steps: a practical guide

Rooted in the synthesis of the effectiveness of medical and psychological interventions in the 1970s (Glass 2015; Gurevitch et al. 2018), meta-analysis is nowadays an established method in management research and related fields.

From living systematic reviews to meta-analytical research domains

Because of the rapidly increasing number of randomised controlled trials (RCTs) and meta-analyses in many fields, there is an urgent need to step up from meta-analyses to higher levels of aggregation

Introducing our series: research synthesis and meta-research in biology

The Research Synthesis Series is brought to BMC Biology to promote meta-analyses, other research syntheses including meta-research studies, and research synthesis methodologies in biology, facilitating their dissemination to broader communities.

A practical guide to preclinical systematic review and meta-analysis

The aim of this review is to highlight the exciting possibilities a preclinical systematic review can bring to your research toolkit, and demonstrate the importance of preclinical SRs in generating empirical evidence to aid robust experimental design, inform research strategy, and support funding applications.

The science of evidence synthesis in hematopoietic stem‐cell transplantation: Meta‐analysis and quality assessment

The opportunity provided by the recent fortieth anniversary of meta‐analysis is taken to reflect on the accomplishments, limitations, and developments in the field of research synthesis in HSCT by summarizing the main methodological features of meta-analysis and its extensions, and by exemplifying the power and evolution of evidence synthesis inHSCT.

PRISMA 2020 statement and guidelines for systematic review and meta-analysis articles, and their underlying mathematics: Life Cycle Committee Recommendations

The paper discussed the overall aspects of systematic review and meta-analysis and explored the main mathematical context of meta-analysis. This included various methods of analyzing the effect size



Making Sense of Meta-Analysis: A Critique of “Effectiveness of Long-Term Psychodynamic Psychotherapy”

Evidence-based practice depends in part on knowledge derived from relevant research. For any given topic, there are likely to be many, potentially relevant studies; a careful appraisal and synthesis

Synthesizing evidence: shifting the focus from individual studies to the body of evidence.

5 reasons to shift the collective focus from single studies to the accumulating body of evidence are offered.

Methodological issues and advances in biological meta-analysis

It is shown how the marriage between mixed-effects (hierarchical/multilevel) models and phylogenetic comparative methods has resolved most of the issues under discussion and how the use of within-study meta-analysis can improve many empirical studies typical of ecology and evolution.

The meta‐analytic big bang

Why meta-analysis came to be in the 1970s in the social sciences through the work of Gene Glass, Robert Rosenthal, and Frank Schmidt, each of whom developed similar theories of meta- analysis at about the same time is examined.

Relative citation impact of various study designs in the health sciences.

Overall, the citation impact of various study designs is commensurate with most proposed hierarchies of evidence, and meta-analyses received more citations than randomized trials when limited to studies addressing treatment effects.

Temporal Trends in Effect Sizes: Causes, Detection, and Implications

the general aim of metaanalysis, as well as of any other form of research synthesis, is to combine scientific evidence scattered through a number of individual studies addressing the same topic.
