All data were obtained retrospectively from medical records, including age, gender, height, body weight, alcohol consumption, hypertension, type 2 diabetes mellitus (T2DM), blood counts, serum biochemistry, coagulation function, alpha-fetoprotein, Hepatitis B surface antigen, HBV DNA, and surgical method and intraoperative blood transfusion. The pathological features of resected tumors (histopathology type, size, numbers, cell differentiation, capsule formation, microvascular invasion, and microsatellite lesions), cirrhosis and hepatic steatosis were recorded. Postoperative complications such as intraabdominal hemorrhage, infection, liver failure, biliary leakage, ascites, and pleural effusion and operative death after hepatectomy were collected. The Child-Pugh score identified patients as grade A (5–6 points), B (7–9 points), or C (10–15points), based on the serum albumin, bilirubin, prothrombin time, and ascites and encephalopathy.
