What the FDA AER plate says about Furunculosis

Signature read: death-coded share at 8.7% is the most distinctive outcome stamp on Furunculosis. Report volume sits in the middle third of the reaction corpus. 9 of 104 reports were death-coded (8.7% of named reports, not a population mortality rate). Nearest volume peer: Application site hot spot (±0 reports). Lead species Dog (99). Lead co-reported drug Oclacitinib Maleate (52).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Oclacitinib Maleate 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.
