1. The delay time between onset of ESRD and first cadaver kidney transplant varies considerably across patient subgroups. It is shortest for Whites and Asian Americans and longest for Blacks. Patients with blood type O and those highly sensitized have longer delays. 2. The effect of delay time on graft survival, while real and statistically significant, is quantitatively small. 3. Based on an analysis of a large national United States sample, CAPD therapy, compared to other forms of dialysis, does not have an adverse effect on 2-year graft survival.
