AS: arterial stiffness; BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; SUA: serum uric acid; LDL: low-density lipoprotein; HDL: high-density lipoprotein; uUA/Cre: urinary uric acid/creatinine ratio; FEUA: fraction excretion of uric acid; baPWV: brachial-ankle pulse wave velocity; CIMT: carotid intima-media thickness. Nonnormally distributed variables are expressed as the median (interquartile range). All other values are expressed as mean ± SD or , %.
