What the FDA AER plate says about Vasculitis

Signature read: 73 death-coded reports is a heavy tail count for Vasculitis in the CVM extract. Report volume is upper-third scale: 356 named reports in the openFDA extract. 73 of 356 reports were death-coded (20.5% of named reports, not a population mortality rate). Nearest volume peer: Closed eyelid (±0 reports). Lead species Dog (296). Lead co-reported drug Carprofen (68).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Carprofen appears in filings alongside this reaction; that is association, not causation. Browse the full reactions index or the about page for how PlainBreed frames FDA CVM extracts.
