a Results of Cox proportional hazards analysis. Relative risk less than or greater than 1.00 indicate a proportionally reduced or increased risk of graft failure. For example, among cadaver donor transplants, recipients who had a preemptive transplant were 25% less likely to experience graft failure compared to nonpreemptive transplants.
