Immune reconstitution posthaploidentical HCT with BM grafts in patients with CRS compared with those without CRS. (A) Treg, Tcon, and CD8+ T-cell counts at 1 month after HCT. (B) PD-1+ Treg cell counts at 1-month after transplantation. The number of samples available for flow cytometry evaluation at each time point for each graph is shown. The Wilcoxon rank-sum test was performed for all group comparisons, with all tests being 2-sided with a significance level of 0.05. The bars in all plots represent median values, with error bars representing the interquartile range between the 25% and 75% quartiles.
