Cumulative incidence curves. (A) Grade 2 to 4 acute GVHD; (B) grade 3 to 4 acute GVHD; and (C) chronic GVHD. Panel C is the cumulative incidence curve of chronic GVHD over ∼36 months of overlapping posttransplant follow-up across trial arms and CIBMTR cohorts. HRs are based on analyses over the entirety of available follow-up for all study cohorts. Two additional chronic GVHD events were observed in the omidubicel arm after 36 months. The cumulative incidence curves are unadjusted, whereas the HRs represent adjusted analyses. Haplo, haploidentical.
