  1. Relations between variables were assessed using non-parametric Spearman's correlation coefficients (ρ). Independent relations were assessed using multivariate regression analysis (β). PON1, paraoxonase 1; LDL, low-density lipoprotein; HDL, high-density lipoprotein; HOMA-IR, homeostasis model assessment- insulin resistance; hsCRP, high sensitivity C-reactive protein; MBF, myocardial blood flow; MFR, myocardial flow reserve; CPT, cold pressor test.
