borderline significanceP = 0.239
The BMI×Weight loss interaction terms were tested for OS, and a borderline significance was identified for the differential impact of weight loss between underweight and overweight/obese patients (normal weight×HWL vs underweight×LWL, P = 0.239; overweight/obese×HWL vs underweight×LWL, P = 0.054; Table S1 ).
