The analysis that reviews various studies on the same topic to find consistent outcomes is known as what?

A meta-analysis is a statistical technique that combines the results of multiple studies to assess the effectiveness or outcomes of a particular intervention or treatment. By aggregating data from various studies conducted on the same topic, it enables researchers to identify patterns and consistency in results that may not be apparent from individual studies alone. This approach provides a more robust conclusion by increasing the sample size and statistical power, thereby allowing for a clearer understanding of the overall impact of a given treatment or intervention.

In contrast, a systematic review evaluates the methodology of research studies and synthesizes findings but may not always involve a statistical combination of data. A literature review provides a comprehensive overview of existing literature on a topic but does not employ rigorous methods for finding consensus or statistical analysis. A case study focuses on an in-depth exploration of a single instance or phenomenon, which does not align with the broader analytical approach of synthesizing multiple studies. Thus, the definition and purpose of meta-analysis distinctly highlight its importance in evidence-based practice.
