Effect of graft source on the following outcomes after allogeneic HSCT. OS (A), CI-NRM (B), CI-relapse (C), acute grade 2 to 4 GVHD (D) and grade 3 to 4 GVHD (E), and chronic GVHD (F). Graft source–related outcomes were confirmed for OS, cumulative incidence of acute GVHD (≥grade 3), and chronic GVHD. Our data demonstrated rapid graft-related IR and revealed the clinical effects of posttransplant outcomes using lymphocyte subset analysis on day 100 after allogeneic HSCT. These results suggest that a specific IR profile after CBT yields superior posttransplant outcomes.
