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).
