Numbers and frequencies of “memory-like” NK cells are associated with the severity of HCMV infection. NK-cell reconstitution was compared in alloSCT recipients who controlled HCMV (controllers, blue), those who experienced csCMVi without Rf/EOD (gray), and those who faced csCMVi with Rf/EOD (red). (A) CD56⁺CD3⁻, CD56^brightCD3⁻ and CD56^dimCD3⁻ NK-cell numbers. (B-C) Absolute cell numbers and frequencies of (B) CD56^dimCD159c⁺(CD57⁺) and (C) CD56^dimCD159c⁺⁺(CD57⁺) “memory-like” NK cells. (A-C) Symbols/lines and error bars indicate medians and interquartile ranges, respectively. Kruskal-Wallis test and Benjamini-Hochberg procedure to test for a FDR of <0.2. The significant result with an FDR >0.2 is indicated by a gray star. ∗P < .05, ∗∗P < .01. CD, cluster of differentiation.
