a Data were tested for normality. 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.
