Signature read: 102 death-coded reports is a heavy tail count for Pyuria in the CVM extract. Report volume is upper-third scale: 640 named reports in the openFDA extract. 102 of 640 reports were death-coded (15.9% of named reports, not a population mortality rate). Nearest volume peer: Pyrexia (±0 reports). Lead species Dog (548). Lead co-reported drug Trilostane (151).

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.
