Kaplan–Meier overall survival (OS) curves of patients with stage I non-small cell lung cancer (NSCLC) stratified by body mass index (BMI). Underweight BMI < 18.5 kg/m2; normal weight BMI 18.5–22.4 kg/m2; overweight BMI 22.5–28.0 kg/m2; and obese: BMI > 28.0 kg/m2. a The OS was longer in the overweight group than in other groups in combination (P = 0.001). b The OS was longer in the overweight group than in the underweight group (P = 0.012), the normal weight group (P = 0.001), and the obese group (P = 0.002)
