Abbreviations: BMI = body mass index. Data are given as mean (SD) unless otherwise indicated. All values are at the start of the initial weight loss program (i.e. month 0).
P-values are calculated for continuous variables using T-test and calculated for categorical variables using Chi-square Test or Fisher’s exact test to compare between groups.
