  1. Continuous data are presented as median (range, interquartile range), whereas categorical data are shown as number of patients. Significant P-values are in boldface
  2. BMI, body mass index; ASA, American Society of Anesthesiologists; HCC, hepatocellular carcinoma; ICGR15, indocyanine green retention rate at 15 min; OR, odds ratio; CI, confidence interval
  3. aMajor hepatectomy indicates more than one section hepatectomy excluding left lateral hepatectomy
  4. bMinor hepatectomy indicates partial and left lateral hepatectomy
  5. cData 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 (with ascites, 8 cases; without ascites, 126 cases)
  6. dData on C-reactive protein were partially lacking (with ascites, 11 cases; without ascites, 117 cases)
  7. eData on ICGR15 were partially lacking (with ascites, 10 cases; without ascites, 130 cases)
  8. fData on total transection time were partially lacking (with ascites, 11 cases; without ascites, 115 cases)
  9. gData on total Pringle maneuver time were partially lacking (with ascites, 9 cases; without ascites, 90 cases)
