Table 2: Lesion 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, TACE = transcatheter arterial chemoembolization, MWA = microwave ablation, RFA = radiofrequency ablation
