Different outcomes after kidney transplantation between African Americans and Whites: A matter of income? A single-center study.

There were 1333 patients in our study, 696 Whites and 637 African Americans. The 1-, 5-, and 10-year graft survival between the two groups was 96.5% vs 91.1%, 89% vs 80.7%, and 77% vs 66.3%, respectively (P < .001 by Log Rank, Breslow and Taron-Ware). When we compared the two groups separately in each income category, we found no statistical difference between African Americans and Whites in graft survival. In the regression model, income and not race was the significant factor influencing graft survival (P < .001 vs P = .61).
