What the FDA AER plate says about Hypertension

Signature read: 236 death-coded reports is a heavy tail count for Hypertension in the CVM extract. Report volume is upper-third scale: 1,324 named reports in the openFDA extract. 236 of 1,324 reports were death-coded (17.8% of named reports, not a population mortality rate). Nearest volume peer: Precipitate, Sediment (±3 reports). Lead species Dog (998). Lead co-reported drug Trilostane (188).

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