a
Non-parametric analysis of covariance was performed to adjust the effect of possible confounding on the observed mean differences. This analysis was based on the ranks of insulin resistance.
b
Waist circumference was entered into the model as a continuous variable. The result of the univariate analysis for this parameter is shown by the Spearman correlation coefficient (r).
