The cumulative incidence (CI) of neutrophil engraftment by day 77 in patients given units with 0-MM (mean TNC, 4.4) or 3-MM (mean TNC, 3.9), or according to the TNC ×107/kg in patients with 1- or 2-MM CB grafts. Note that the 4 TNC categories in this figure exclude those that had either 0 or 3 mismatches, accounting for the lower number of cases in each TNC group in the figure compared with Table 2.
