A composite analysis of CKD development and progression was performed in CKD-naïve and preexisting CKD groups (). Analysis for the development of ESRD was performed in all subjects (). Data are shown as HR (95% confidence interval). , , adjusted for age, sex, body mass index, systolic blood pressure, high-density lipoprotein cholesterol, antihypertensive, and glucose-lowering agents. Abbreviations: CKD: chronic kidney disease; ESRD: end-stage renal disease; HR: hazard ratio; CI: confidence interval.
