What the FDA AER plate says about Stress leukogram

Signature read: 42 death-coded reports is a heavy tail count for Stress leukogram in the CVM extract. Report volume sits in the middle third of the reaction corpus. 42 of 204 reports were death-coded (20.6% of named reports, not a population mortality rate). Nearest volume peer: INEFFECTIVE, PRODUCTION (MILK) (±0 reports). Lead species Dog (171). Lead co-reported drug Trilostane (53).

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.
