DM: diabetes mellitus; BMI: body mass index; SBP: systolic blood pressure; PP: pulse pressure; HbA1c: hemoglobin A1c; eGFR: estimated glomerular filtration rate; HDL: high density lipoprotein; LDL: low density lipoprotein; hsCRP: high-sensitivity C-reactive protein; HOMA-IR: homeostasis model assessment-insulin resistance; CIMT: carotid intima-media thickness; ABI: ankle-brachial index; baPWV: brachial-ankle pulse wave velocity.

Spearman’s correlation analysis was used for the statistical analyses.
