Abbreviations: BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); BMIz, BMI z score.
a
Value: adjusted parameters from mixed-effects regression models reflecting differences between groups over 6-month, 12-month, and 24-month assessments.
b
Outcomes assessed only at 6-month and 24-month assessments. All models include planned covariates for age, sex, time, and corresponding baseline values.
