¹Significant differences were observed between minimal hepatic encephalopathy patients and non-minimal hepatic encephalopathy patients.

MHE: Minimal hepatic encephalopathy; MELD: Model for end-stage liver disease; ALT: Alanine transaminase; AST: Aspartate transferase; INR: International normalized ratio; ALB: Albumin; Cr: Creatinine; WBC: White blood cell; HGB: Hemoglobin; PLT: Platelet.
