a
Results for Time Interval are reported as mean (minimum to maximum).
b
Results for Weight (and BMI) and Change reported as mean (SE), adjusted for age, sex, weight (or BMI) at Start of the FBBI. P-values at 6 months assess the statistical significance of measurements between 0 and 6 months. P-values at 12 and at 18 months assess the statistical significance of measurements between FBBI-C and FBBI-M groups.
