The table presents median and IQR for change in BMI percentile compared with BMI at time of surgery for the overall data set and each BMI cohort (normal weight, overweight, and obese). The change in BMI percentile for the overall data set is depicted in Figure 1, and the change by obesity categorization is depicted in Figure 2.
