| ALT – alanine aminotransferase; AST – aspartate aminotransferase; BMI – body mass index; EGVB – esophageal gastric-fundus variceal bleeding; HBV – hepatitis B virus; HCV – hepatitis C virus; HU – Hounsfield units; INR – international standardization ratio; MELD – model for end-stage liver disease; MELD-Na – composite index of model for end-stage liver disease and serum sodium; PMD – psoas muscle density; RBC – red blood cell count; RF – refractory ascites; TIPS – transjugular intrahepatic portosystemic shunt; WBC – white blood cell count. a Descriptive statistics are expressed as numbers or mean values (±SD), as appropriate. Continuous variables are expressed as means±SD or medians with interquartile ranges. b The test or the Mann-Whitney U test was used to compare 2 groups, and χ test or Fisher exact test was used to compare categorical variables. c Others included primary biliary cirrhosis, autoimmune diseases, Budd-Chiari syndrome, and cryptogenic cirrhosis. d Others included preventive therapy, portal system thrombosis, and alleviation of abdominal discomfort. e Others included portal vein trunk, right branches of the portal vein, and confluence of the left branches of the portal vein. | ||||
