Quantitative variables are expressed as mean and standard deviation, while qualitative variables are expressed as absolute (n) and relative values (%). The t-test was used for comparison of patient's age between the two groups. The χ² test was used for sex (male). Fisher’s exact test was used for etiologies of hepatectomy, type of hepatectomy, and intraoperative transfusion. BMI: Body mass index.
