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 presented as hazard ratio (95% confidential interval). ,†. Abbreviations: HbA1c: glycated hemoglobin; BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; LDL: low-density lipoprotein; HDL: high-density lipoprotein; eGFR: estimated glomerular filtration rate.
