Combining Data from Multiple Studies.

Abstract

Meta-analysis is a valuable statistical tool in medical research. It allows researchers to combine data from multiple studies to produce more robust and reliable estimates of the intervention effects, particularly when individual studies have limited sample sizes and/or conflicting findings. By quantitatively synthesizing evidence from multiple sources, meta-analysis can provide a more comprehensive and holistic perspective on the available evidence and help inform decision-making and policy implementation in health care.¹.
