The Largest Transplant Gap Was Among Younger Indigenous Adults

An average inequality can hide the age groups for whom the difference is greatest and most consequential. Among adults aged 18–40, 20.6% of Indigenous patients versus 48.3% of white patients received a transplant; the adjusted hazard ratio was 0.50. The disparity attenuated with age and was not statistically evident in the oldest group. The age interaction shows why one population-average estimate is too blunt and why access mechanisms may operate differently across the life course.
