Caveat (required reading): 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 is a reporting baseline (average device in the same product code), not a risk measure.
