Pooled analysis is a type of research methodology that involves combining data from multiple studies in order to increase statistical power and provide more robust conclusions. This approach allows researchers to draw more reliable conclusions by aggregating and analyzing data from various sources, often leading to more generalizable results. Pooled analysis can be particularly useful in meta-analyses or systematic reviews, where data from numerous studies are synthesized to provide a more comprehensive understanding of a particular research question or topic. This method can help researchers identify trends, patterns, and associations that may not be apparent in individual studies alone, making it a valuable tool in evidence-based medicine and other research fields.
