What the FDA AER plate says about Low sodium-potassium ratio (Na:K ratio)

Signature read: 163 death-coded reports is a heavy tail count for Low sodium-potassium ratio (Na:K ratio) in the CVM extract. Report volume is upper-third scale: 1,134 named reports in the openFDA extract. 163 of 1,134 reports were death-coded (14.4% of named reports, not a population mortality rate). Nearest volume peer: Anaphylactic-type reaction (±2 reports). Lead species Dog (1,074). Lead co-reported drug Trilostane (1,140).

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.
