Reconstitution of CD4Tregs, CD4Tcons, and CD8 T cells according to cGVHD status 9 months after transplant. (A) CD4Treg:CD4Tcon and CD4Treg:CD8 ratios. (B) The percentages of CD4Tregs, CD4Tcons, and CD8 T cells. (C) Proliferation (%Ki67) in CM CD4Tregs. Each figure compares patients with (red) and without (blue) cGVHD. Box plots in panels A and B depict the 75th percentile; median and 25th percentile values and whiskers represent maximum and minimum values. In panel C, dots depict the number of patients (n = 20 for each group) and the whiskers correspond to the 75th and 25th percentile. cGVHD, chronic GVHD.
