Elevated fibrinogen level: high death-coded share in the FDA AER plate
Signature read: Elevated fibrinogen level's 32.9% death-coded share is among the highest in the openFDA reaction corpus. Report volume sits in the middle third of the reaction corpus. Death-coded share is upper-third: 25 of 76 reports (32.9% of named reports). Nearest volume peer: Adaptor, abnormal (±0 reports). Lead species Horse (45). Lead co-reported drug Polysulfated Glycosaminoglycan (13).
Read these counts as reporting volume, not risk: per our methodology, A high death-coded share in FDA filings does not prove causation; co-reporting is voluntary temporal association only. Browse the full reactions index or the about page for how PlainBreed frames FDA CVM extracts.
