Figure 1.
Kaplan-Meier Estimates of 5-year Graft Survival Among Medicare-extension “Eligible” Graft Recipients Stratified by Income Level and Era of Transplantation.
A) Patients who received Medicare's lifetime coverage (Cohort 1).
B) Patients transplanted too soon to qualify for Medicare's lifetime-coverage (Cohort 2). There was no difference in 5-year graft survival between the highest income quartile (Q4) shown in blue and the lowest income quartile (Q1) shown in black when patients received lifetime coverage but better allograft survival among higher income recipients when lifetime-coverage was not available, P=0.039.
