The Proportional Reporting Ratio (PRR) is a statistical measure used in pharmacovigilance to assess the strength of a signal regarding adverse drug reactions (ADRs) associated with a specific drug. It helps to compare the frequency of reported adverse effects for a particular drug to the frequency of those effects for other drugs or across the overall population of reported cases.
