What the FDA AER plate says about Urolithiasis

Signature read: 66 death-coded reports is a heavy tail count for Urolithiasis in the CVM extract. Report volume sits in the middle third of the reaction corpus. 66 of 335 reports were death-coded (19.7% of named reports, not a population mortality rate). Nearest volume peer: Crackles on auscultation (±0 reports). Lead species Dog (296). Lead co-reported drug Milbemycin Oxime + Spinosad (64).

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.
