What the FDA AER plate says about Oral mass

Signature read: 55 death-coded reports is a heavy tail count for Oral mass in the CVM extract. Report volume sits in the middle third of the reaction corpus. 55 of 239 reports were death-coded (23.0% of named reports, not a population mortality rate). Nearest volume peer: Aural haematoma (±0 reports). Lead species Dog (204). Lead co-reported drug Oclacitinib Maleate (99).

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.
