Acute‐on‐chronic liver failure precipitated by hepatic injury is distinct from that precipitated by extrahepatic insults

ACLF precipitated by hepatic insults is distinct from ACLF precipitated by extrahepatic insults in clinical presentation and prognosis. The iMELD score may be a better predictor for hepatic-ACLF short-term prognosis, whereas CLIF-C-ACLF may be better for extrahepatic-ACLF patients.
