Comparison of T-cell development in haplotransplanted patients without GVHD or GT-treated patients. The absolute peripheral blood (A) CD3⁺, (B) CD3⁺CD4⁺, and (C) CD3⁺CD8⁺ lymphocyte count in haplotransplanted patients without clinical GVHD and GT patients at 6, 12, and 24 months and 5 years. (D) Absolute number of peripheral blood CD3⁺CD4⁺ lymphocytes expressing CD45RA and CD31 in haploidentical HSCT patients without GVHD or GT patients at 6, 12, and 24 months and 5 years after transplantation. Extremities of the whiskers boxes represent minimum and maximum values. Bottom and top of the box represent the first and third quartiles, respectively. The horizontal bar in the box represents the median value.
