Rates of neutrophil and platelet engraftment by treatment arm. (A) Omidubicel demonstrated faster neutrophil engraftment than other donor sources. Standard UCB transplantation had the slowest neutrophil recovery. HR was expressed relative to omidubicel as reference. All analyses were adjusted for baseline characteristics as defined in “Methods.” (B) Both omidubicel and standard UCB showed slower rates of platelet engraftment relative to alternative donor sources from CIBMTR. The cumulative incidence curves are unadjusted, whereas the HRs represent adjusted analyses. Haplo, haploidentical.
