Note. Values of age, SRM, and ALI are grand mean centered. BMI stands for Body Mass Index. Model A tests proposed covariates. Model B is the best-fitting covariate model. Model C tests the first hypothesis examining whether the SRM index at baseline moderates an increase in waist circumference (WC). Model D tests the second hypothesis examining whether ALI at baseline moderates an increase in WC.
