What the FDA AER plate says about Haemoconcentration

Signature read: 60 death-coded reports is a heavy tail count for Haemoconcentration in the CVM extract. Report volume sits in the middle third of the reaction corpus. 60 of 289 reports were death-coded (20.8% of named reports, not a population mortality rate). Nearest volume peer: Application site dermatitis (±0 reports). Lead species Dog (264). Lead co-reported drug Maropitant Citrate (49).

Read these counts as reporting volume, not risk: per our methodology, Lead co-reported drug Maropitant Citrate 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.
