Cumulative incidence aGVHD and cGVHD. The cumulative incidence (CI) of GVHD is defined as time to onset of GVHD, with relapse and death as competing events. (A) CI of aGVHD ≥grade 2-4 (left) and aGVHD ≥3-4 (right). (B) CI of mild cGVHD (left), moderate GVHD (right), or severe cGVHD (bottom left). Dashed lines indicate a 95% confidence interval (95% CI).
