  1. Continuous data are presented as median (range, interquartile range), whereas categorical data are shown as number of patients
  2. BMI, body mass index; ASA, American Society of Anesthesiologists; HCC, hepatocellular carcinoma; CCC, cholangiocellular carcinoma; meta, liver metastasis; HCV, hepatitis C virus; HBV, hepatitis B virus; ASH, alcoholic steatohepatitis; NASH, non-alcoholic steatohepatitis; ICGR15, indocyanine green retention rate at 15 min
  3. aData on liver fibrosis were partially lacking (monopolar, 62 cases; bipolar, 61 cases)
  4. bData on the size of the largest nodule and number of nodules were partially lacking because biliary tract cancer and benign disease could not be accurately measured (monopolar, 66 cases; bipolar, 68 cases)
  5. cData on C-reactive protein were partially lacking (monopolar, 71 cases; bipolar, 57 cases)
  6. dData on ICGR15 were partially lacking (monopolar, 70 cases; bipolar, 70 cases)
