Gastric cancer-specific survival distributed by sex and body mass index (BMI) according to treatment modality. Endoscopic treatment in males (A) and in females (B). Operative treatment in males (C) and in females (D). Chemotherapy in males (E) and in females (F). Conservative treatment in males (G) and in females (H). Cumulative survival was calculated using Kaplan-Meier estimates; the p-values were calculated using the log-rank test. Predefined BMI categories according to Asia-Pacific World Health Organization criteria were used: underweight, BMI <18.5 kg/m2; normal, BMI 18.5 to 22.9 kg/m2; overweight, BMI 23.0 to 24.9 kg/m2; obesity, BMI 25.0 to 29.9 kg/m2; severe obesity, BMI ≥30.0 kg/m2.
