Percent panel reactive antibody (%PRA) taken at various time points (A: at time of graft failure/allograft nephrectomy, B: 6 months after graft failure/allograft nephrectomy, and C: last follow-up) in patients who received early allograft nephrectomy (<6 months post-transplant, black circles) and those who were maintained on immunosuppression despite early graft failure (<6 months post-transplant, black squares). *p < 0.05 vs. pre-transplant, †p = 0.02 vs. A, ‡p < 0.05 between the 2 groups; TX: transplant.
