What the FDA AER plate says about Elevated gamma-glutamyl transferase (GGT)

Signature read: 631 death-coded reports is a heavy tail count for Elevated gamma-glutamyl transferase (GGT) in the CVM extract. Report volume is upper-third scale: 3,047 named reports in the openFDA extract. 631 of 3,047 reports were death-coded (20.7% of named reports, not a population mortality rate). Nearest volume peer: Seal, Abnormal (±2 reports). Lead species Dog (2,781). Lead co-reported drug Trilostane (809).

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.
