The research procedure that involves statistically combining the results of multiple studies is meta-analysis. This method allows researchers to quantitatively assess the overall effects, patterns, and relationships found in a body of research by integrating results from various studies. By performing statistical calculations, meta-analysis enables a comprehensive evaluation of evidence, helping to identify trends that may not be apparent from individual studies alone.

Meta-analysis often includes rigorous criteria for study selection, ensuring that only relevant, high-quality studies contribute to the analysis. This strengthens the validity of the conclusions drawn from the combined data. In contrast, while systematic reviews aim to summarize and evaluate the available research on a specific topic, they do not necessarily perform statistical analysis on the data from each study. Literature reviews provide a broad overview of research findings and trends without the structured rigor of systematic reviews or the statistical focus of meta-analysis. Pooling analysis, while it may sound similar, is not a standard term and is not recognized as a specific type of research procedure in the same way that meta-analysis is.
