  • Univariable analysis was executed before adjustment with other variables. The cutoff value in iPTH was the median value. HR, hazard ratio; 95% CI, 95% confidence interval; PKT, preemptive kidney transplantation; NA, not applicable; iPTH, intact parathyroid hormone; CVD, cardiovascular disease; LVH, left ventricular hypertrophy.
