Univariate analysis revealed that testosterone levels were associated with waist circumference (inversely), diastolic blood pressure (BP) (inversely), mean BP (inversely), triglycerides (inversely), high-density lipoprotein-cholesterol (HDL-cholesterol), fasting plasma glucose (inversely), fasting insulin (inversely), homeostasis model assessment of insulin resistance (HOMA-IR) (inversely), AGEs (inversely) and uric acid (inversely).

^†Log-transformed value was used. LDL-cholesterol, low-density lipoprotein-cholesterol; HbA1c, glycosylated hemoglobin; Hs-CRP, high sensitive C-reactive protein; β, regression coefficients; SE, standard error.
