  1. Continuous variables were presented as mean (standard error) and examined using the Student’s t test. Categorical variables were estimated using Fisher’s exact test. ALT, serum alanine aminotransferase; Cr, serum creatinine; INR, international normalized ratio of prothrombin time; METAVIR A, activity; METAVIR F, fibrosis; Na, serum sodium; SWV, shear wave velocity.
