GVHD Outcomes. (A) Cumulative incidence (CI) of grade 2 to 4 aGVHD. (B) CI of grade 3 to 4 aGVHD. (C) CI of any cGVHD. (D) CI of moderate-severe GVHD. (E) CI of severe cGVHD. (F) CI of being taken off immunosuppressive therapy (IST); ∗all CIs reported are competing with death, relapse, or graft failure. For aGVHD, competing risks also include cGVHD (without prior acute). ∗P value for differences in cumulative incidence obtained using Gray method.
