Pooled Risk Ratios (RRs): Combining Study Results for Overall Risk

Pooled risk ratios (RRs) are statistical measures used in meta-analysis to combine the results of multiple studies and calculate the overall risk ratio for a specific outcome or exposure. The risk ratio compares the risk of a particular outcome or exposure in the treatment group to the risk in the control group. Pooled risk ratios are calculated by combining the individual risk ratios from each study and weighting them according to the sample size of each study. Pooled risk ratios are used to determine the overall effect size of an intervention or exposure on a specific outcome, and can help to identify patterns and trends across multiple studies.
