**There is no standard deviation for this data point because all patients in this cohort were continuously enrolled 63 months).

Figure 1. Mean BMI by year and weight change from index period. Bars represent the percentage of patients that gained >3% weight (red bar), maintained their weight (yellow), or lost >3% weight (green) in comparison to the previous year. Mean body mass index (BMI) for each year is indicated with the blue line.
