Cumulative incidence of grade II-IV acute GVHD and Kaplan-Meier estimates of OS, DFS and EFS. (A) Cumulative incidence of grade II-IV acute GVHD (aGVHD) for patients given BM and CB transplantation. (B) Kaplan-Meier estimate of OS for patients given BM and CB transplantation. (C) Kaplan-Meier estimate of DFS for patients given BM and CB transplantation. In the calculation of DFS, both death and graft failure were considered events. (D) Kaplan-Meier estimate of EFS for patients given BM and CB transplantation. In the calculation of EFS, death, graft failure, and extensive chronic GVHD were considered events.
