EASL/AASLD/APASL/ALEH/SOLDA — Acute-on-chronic liver failure: a global multisociety consensus on definitions

Harmonizes advanced liver disease, hepatic failure, extrahepatic dysfunction/failure and prior-decompensation phenotypes. Use its own grading explicitly; historical cohorts and scores cannot simply be relabeled. Recommendation-specific evidence varies; this scope record does not assign one GRADE rating to every statement.
