¹Models adjusted for candidate age, birth sex, blood type, calculated panel reactive antibody at listing, time on dialysis, diagnosis, history of peripheral vascular disease, prior transplant, distance from transplant center, education, social vulnerability index, and year of listing. Model excludes body mass index. sHR: Sub-distribution hazard ratio; CI: Confidence interval.
