Hypopigmentation: low death-coded share in the FDA AER plate
Signature read: 3 death-coded reports is a thin tail count for Hypopigmentation in the CVM extract. Report volume sits in the middle third of the reaction corpus. Death-coded share is lower-third: 3 of 68 reports (4.4% of named reports). Nearest volume peer: Chewing disorder (±0 reports). Lead species Dog (58). Lead co-reported drug Toceranib Phosphate (12).
Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Toceranib Phosphate 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.
