Largely developed in the 1970s, meta-analysis has become an important research tool throughout many scientific domains. In the healthcare professions, meta-analysis plays a particularly prominent role in answering large questions about interventions (e.g., Is a certain intervention efficacious?) through a quantitative integration of many research findings offering evidence on the question. That is, meta-analysis is an objective means for establishing the weight of scientific evidence bearing on a clinical question that may embody broad policy implications.
As its name implies, a metaanalysis is an analysis of analyses. The analyses are the findings reported in journal articles, platform presentations, theses, unpublished manuscripts, and so forth. In a meta-analysis, these reports of original research are termed primary studies. A meta-analysis is nothing more than an analysis of results taken from multiple primary studies addressing a common research question (e.g., all studies addressing the impact of group treatment on levels of functional communication).
