Prevalence of positive MRD by BMI percentile. To illustrate the relationship between MRD status and BMI percentile as a continuous variable without regard to CDC-defined thresholds, a monotone nondecreasing logistic model was fit to the data (curved line; error bars correspond to 95% confidence intervals for each of the 6 equal groups [n = 33 per group]). This showed an increased prevalence of MRD positivity at the highest BMI percentiles as depicted in the figure. The significance of this finding was confirmed via permutation test (P = .02).
