Table 3.
BMI-related outcomes at 6 and 12 months for responders at 1 month (at least 3% BMI reduction) vs. non-responders at 1 month (less than a 3% BMI reduction) adjusted for age, sex, race (Caucasian vs. other), ethnicity, and baseline BMI with robust variance estimation. At 6 months: responder n=97, non-responder n=512 (total n=609); at 12 months: responder n=44, non-responder n=218, total n=262). Results are represented as the absolute mean (standard deviation, SD) BMI change (kg/m2), the percent BMI change (%), 95th BMI percentile change (%), and the BMI z-score change. R=responder, NonR=non-responder, CI=confidence interval.
