What the FDA AER plate says about Hyperthermia
Signature read: 255 death-coded reports is a heavy tail count for Hyperthermia in the CVM extract. Report volume is upper-third scale: 1,557 named reports in the openFDA extract. 255 of 1,557 reports were death-coded (16.4% of named reports, not a population mortality rate). Nearest volume peer: Azotaemia (±0 reports). Lead species Dog (914). Lead co-reported drug Buprenorphine (347).
Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Buprenorphine 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.
