There were no significant differences between the two groups regarding age, weight, BMI, fasting and two-hour glucose and insulin levels, insulin resistance indices (HOMA and Matsuda), lipid levels (total cholesterol, LDL, HDL), systolic and diastolic blood pressure, endothelial dysfunction (FMD) and the circulating adiponectin (Table 1). This evidence concerns the gene ADIPOQ and endothelial dysfunction.
