What the FDA AER plate says about Seroma

Signature read: 12 death-coded reports is the most distinctive absolute-outcome stamp on Seroma. Report volume sits in the middle third of the reaction corpus. 12 of 96 reports were death-coded (12.5% of named reports, not a population mortality rate). Nearest volume peer: Cardiac failure (±0 reports). Lead species Dog (67). Lead co-reported drug Carprofen (22).

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.
