Note: Biomarkers are grouped into categories of adipokines, cytokines, hormones/growth factors, and insulin. A total of 25 biomarkers or ratios were assessed. There is no adjustment for multiple comparisons so caution is advised in interpretation of the results.
Wilcoxon nonparametric signed-rank test, two-tailed, for within-group differences between baseline and 6 months.
