Immune reconstitution after MSD vs UCB RIC allogeneic transplant. (A) Absolute lymphocyte count; (B) total NK cells (CD3⁻CD56⁺); (C) total CD3⁺ T cells; (D) total CD8⁺ T cells; (E) total CD4⁺ T cells; (F) naïve CD4⁺ T cells (CD45RA⁺CD27⁺); (G) T regulatory cells (CD4⁺CD25^bright CD127); and (H) B cells. The boxes show the interquartile range of absolute cell count (/μL) for each immune cell type. The bold horizontal lines inside the boxes indicate the median absolute cell count (/μL); the whiskers represent 1.5× the height of the box (or minimum/maximum values if there is no value in that range); and the circles indicate the outliers.
