What the FDA AER plate says about Exercise intolerance

Signature read: 49 death-coded reports is a heavy tail count for Exercise intolerance in the CVM extract. Report volume sits in the middle third of the reaction corpus. 49 of 294 reports were death-coded (16.7% of named reports, not a population mortality rate). Nearest volume peer: Abortion (±0 reports). Lead species Dog (285). Lead co-reported drug Milbemycin Oxime + Spinosad (47).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Milbemycin Oxime + Spinosad 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.
