1 From GEE models adjusted for gender, age, site, and baseline BMI: E(Y) = α + β1group + β2time + β3group × time + β4gender + β5age + β6site + β7 (baseline BMI). All biomarker variables are log-transformed to improve normality. Ns differ slightly for some biomarker variables.2 Test for within-group difference in change from baseline to post-intervention visit: * p < 0.05, ** p < 0.01, and *** p < 0.001. 3 Test for difference between groups in change from baseline to post-intervention visit. BMI = body mass index; VAT = visceral adipose tissue.
