aAnalyzed using multilevel mixed-effects linear regression. All models included age, sex, and race as covariates; age and race were significant covariates at P < .05. The 95% CIs that do not include 0 indicate a statistically significant result. Missing observations were as follows: change in body weight (% and kg): month 6 = 66 missing observations, month 12 = 88 observations, month 18 = 100 observations, month 24 = 97 observations; change in waist circumference: month 6 = 69 missing observations, month 12 = 93 observations, month 18 = 103 observations, month 24 = 100 observations.
