Reconstitution of NK-cell populations after haplo-HCT and MD-HCT. (A) Representative gating strategy used to define NK-cell subsets based on expression of CD56 and CD16. (B) Reconstitution of NK-cell subsets after haplo-HCT and MD-HCT. Values are expressed as median and range. (C) Absolute number of NK-cell subsets in peripheral blood after haplo-HCT and MD-HCT. Median cell counts per microliter are represented at each time point. (D) Median CD56^brightCD16⁻/CD56^dimCD16⁺ NK-cell ratio after haplo-HCT and MD-HCT. Statistically significant differences are noted (****P < .0001; ***P < .001; **P < .01; *P < .05; Wilcoxon rank-sum test). See supplemental Table 9 for the median absolute values along with the corresponding interquartile values and P values for panels C and D.
