eGFR, estimated glomerular filtration rate; HbA1c, glycosylated hemoglobin; HDL, high-density lipoprotein; baPWV, brachial-ankle pulse wave velocity; ASCVD, atherosclerotic cardiovascular disease.

^aData were transformed logarithmically to a normal distribution: cystatin C, creatinine, total cholesterol, and HDL-cholesterol.
