Patients were divided into CD group and control group based on baseline levels of C3 (cutoff value, 0.75 mg/mL). Data present with mean ± SD or number (percentage of column). CD, complement depletion; BMI, body mass index; HTN, hypertension; DM, diabetes mellitus; ASA, American Society of Anesthesia; diff., differentiation. plus means extended lymphadenectomy beyond stations during gastrectomy.
