Simple regression analysis between vascular reactivity, abdominal fat distribution, adiponectin and insulin sensitivity index (M) in men without (n = 18, open circles) or with (n = 19, gray circles) metabolic syndrome. FBF at an Ach infusion of 400 nmol/min, FBF at an SNP infusion of 30 nmol/min, and ∆Ach-induced maximal FBF by co-infusion of L-NMMA at 8 μmol/min. Pearson’s correlation coefficients and p values are shown
