What the FDA AER plate says about Iris disorder

Signature read: death-coded share at 22.6% is the most distinctive outcome stamp on Iris disorder. Report volume sits in the middle third of the reaction corpus. 21 of 93 reports were death-coded (22.6% of named reports, not a population mortality rate). Nearest volume peer: Anterior uveitis (±0 reports). Lead species Dog (63). Lead co-reported drug Milbemycin Oxime + Spinosad (11).

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.
