Proportional Reporting Ratio(The proportional reporting ratio (PRR)[1][2][3][4] is a statistic that is used to summarize the extent to which a particular adverse event, or "side effect" is observed for individuals taking a specific drug, compared to the frequency at which the same adverse event occurs for patients taking some other drug (or who are taking any drug in a specified class of drugs). The PRR will typically be calculated using a surveillance database in which reports of adverse events from a variety of drugs are recorded. MusicalTree)
