Clinical outcomes of patients according to BMI category. BMI categories are as follows: underweight (BMI ≤ 10th percentile, n = 102), normal weight (BMI > 10th and < 85th percentile, n = 400), at risk of overweight (BMI ≥ 85th and < 95th percentile, n = 64), or overweight (BMI ≥ 95th percentile, n = 55). Shown are Kaplan-Meier estimates of (A) overall survival; (B) event-free survival; and (C) cumulative incidence of relapse.
