What the FDA AER plate says about Melanoma

Signature read: death-coded share at 23.6% is the most distinctive outcome stamp on Melanoma. Report volume sits in the middle third of the reaction corpus. 30 of 127 reports were death-coded (23.6% of named reports, not a population mortality rate). Nearest volume peer: Cyst NOS (±0 reports). Lead species Dog (123). Lead co-reported drug Oclacitinib Maleate (66).

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.
