Table 1: Patient characteristics.

The numerical data are summarized as mean ± standard deviation or median (*) and the categorical data are shown as frequency (percentage). HCC = hepatocellular carcinoma, ICC = intrahepatic cholangiocarcinoma, FNH = focal nodular hyperplasia, MELD = Model For End-Stage Liver Disease, Child-Pugh= Child-Turcotte-Pugh-Score, NASH= nonalcoholic fatty liver disease, PSC = primary sclerosing cholangitis, ECOG = Eastern Cooperative Oncology Group, BCLC = Barcelona Clinic Liver Cancer, HKLC = Hong Kong Liver Cancer classification system.
