Gingival hyperplasia: low death-coded share in the FDA AER plate

Signature read: Gingival hyperplasia's 3.0% death-coded share is among the lowest in the openFDA reaction corpus. Report volume is upper-third scale: 493 named reports in the openFDA extract. Death-coded share is lower-third: 15 of 493 reports (3.0% of named reports). Nearest volume peer: Sickness (±2 reports). Lead species Dog (453). Lead co-reported drug Cyclosporine (279).

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