Adverse-event reports (MAUDE)

Read this first: MAUDE report counts cannot be used to compute incidence rates or compare device safety. Reporting is incomplete, duplicated, and spikes with publicity; there is no denominator of devices in use. The peer line shows reporting volume for the average device in the same FDA product code — a reporting baseline, not a risk measure.
