  1. Data are expressed as frequencies (percentages), otherwise indicated; The chi-squared (χ²) test or Fisher’s exact test is used to compare these data differences between the groups.
  2. BMI, body mass index; ASA, American Society of Anesthesiologists; HBV, hepatitis B virus; INR, international normalized ratio; PLT, platelets; ALT, alanine aminotransferase; AST, aspartate aminotransferase; CEA, carcinoembryonic antigen; CA19-9, carbohydrate antigen 19 − 9.
  3. a. Data are expressed as mean ± standard deviation.
  4. b. The Mann-Whitney U test is used to compare the differences in these data between the groups.
