Continuous Medicare Parts A\/B coverage 12\u2009months before and after diagnosis or until death, and Part D coverage for 12\u2009months following diagnosis or until death were required for inclusion. We explored time to treatment initiation by race across three diagnosis time periods (2007\u201310, 2011\u20132014, 2015\u20132017) using Cox proportional hazard models.

Black\/White differences in the cumulative incidence of treatment initiation at 3, 6, and 12\u2009months were also significant and persistent across time periods, ranging from 0.09 (95% CI: 0.02, 0.15) to 0.11 (95% CI: 0.05, 0.17).
