Renal Transplants from Older Deceased Donors: Use of Preimplantation Biopsy and Differential Allocation to Dual or Single Kidney Transplant according to Histological Score Has No Advantages over Allocation to Single Kidney Transplant by Simple Clinical Indication

Table 5

Mean restricted number (95% confidence intervals) of functioning graft years by transplant reference (MNFGY) at 1, 3, and 5 years after transplantation, and calculated total number of dialysis-free life years for every 100 donors (TNDFY) at the same times in recipients, in the pre-DKT and DKT protocols. Differences shown in bold indicate a significant statistical difference (P < 0.05).
