What the FDA AER plate says about Red mucosae

Signature read: death-coded share at 22.9% is the most distinctive outcome stamp on Red mucosae. Report volume sits in the middle third of the reaction corpus. 19 of 83 reports were death-coded (22.9% of named reports, not a population mortality rate). Nearest volume peer: Destructive behaviour (±0 reports). Lead species Dog (71). Lead co-reported drug Milbemycin Oxime + Spinosad (10).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Milbemycin Oxime + Spinosad 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.
