The primary objective of a meta-analysis is to synthesize results from multiple studies. This involves statistically analyzing a collection of studies that address a similar research question to derive more comprehensive insights and conclusions than any individual study could provide. By aggregating data, meta-analysis helps improve the precision of estimates, assess the consistency of findings across studies, and identify patterns that may not be apparent when looking at a single study in isolation. This approach enhances the reliability and validity of the conclusions drawn, making it a powerful tool in evidence-based research.

In meta-analyses, researchers consider factors such as study design, sample size, and effect sizes to provide a meaningful overall assessment. This ability to collate and interpret diverse findings significantly contributes to the advancement of knowledge in various fields, such as medicine, psychology, and social sciences.
