TTR10 during the first 4 weeks post-transplantation-based comparison of cumulative incidence of acute GVHD (Grade II–III) during the observation period in all transplant episodes. Solid (n = 14) and dotted lines (n = 66) indicate the Kaplan–Meier curve of the TTR10 ≦ 75.9% and 75.9%< TTR10 groups, respectively. GVHD, graft-versus-host disease; TTR10, time in the therapeutic range at a tacrolimus concentration of ≥ 10 ng/mL.
