Model 1: non-adjusted model.
Model 2: adjustment for age, sex, smoking history, drinking history, BMI, eGFR ALB level, methods of anesthesia, and presence of chronic diseases (hypertension, diabetes, coronary heart disease, chronic obstructive pulmonary disease).
NA: unable to analyze due to few postoperative complication events.
