Data are expressed as median [interquartile range] or (%), as appropriate. p values were determined by using Wilcoxon rank-sum test or -test, as appropriate, for comparison between the CKD and non-CKD groups. , for all subjects, for the non-CKD group, and for the CKD group not receiving insulin therapy. CKD, chronic kidney disease; BMI, body mass index; BP, blood pressure; smoker, prevalence of current or past smokers; DPP, dipeptidyl peptidase; OHA, oral antihyperglycemic agent; statin, prevalence of subjects treated with stains; ARB/ACEI, prevalence of subjects treated with angiotensin II receptor antagonists or ACE inhibitors; HbA1c, glycated hemoglobin A1c; HOMA-R, homeostasis model assessment of insulin resistance; eGFR, estimated glomerular filtration rate; HDL, high-density lipoprotein; LDL, low-density lipoprotein; CTRP, C1q/TNF-related protein; IMT, intima-media thickness.
