HR, hazard ratio.

^*Bold indicates significance at p < 0.05.

Model 1 unadjusted.

Model 2 adjusted for: age and gender.

Model 3 adjusted: model 2+ history of diabetes and cardiovascular disease, serum levels of hemoglobin, high sensitive C-reactive protein, intact parathyroid hormone, systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride, low-density lipoprotein cholesterol, residual renal function, and uses of phosphate binders, calcitriol, and α-ketoacid.
