HE: hepatic encephalopathy; TB: total bilirubin; ACLF: acute-on-chronic liver failure; EASL criteria: (1) patients with single kidney failure, (2) patients with single failure of the liver, coagulation, circulation, or respiration who had a serum creatinine level ranging from 1.5 to 1.9 mg/dL and/or mild to moderate hepatic encephalopathy, and (3) patients with single cerebral failure who had a serum creatinine level ranging from 1.5 to 1.9 mg/dL.
