  1. allo-HSCT allogeneic haematopoietic stem cell transplantation, PGF poor graft function, GGF good graft function, AML acute myelogenous leukemia, ALL acute lymphocytic leukemia, CML chronic myelogenous leukemia, MDS myelodysplastic syndrome, sAA sever aplastic anemia, HLA human leukocyte antigen, BU busulfan, CY cyclophosphamide; ATG anti-human thymus globulin; aGvHD acute graft-versus-host disease, CMV cytomegalovirus
  2. * Group matching criteria included age at HSCT (±1 years), pre-HSCT cycles of chemotherapy (±1 cycle), disease status at HSCT and BM microenvironment evaluated time after HSCT (±5 days). For each PGF case, two GGF control was randomly selected from the same cohort at which the PGF occurred (“risk-set sampling”)
  3. ** The continuous variables were compared using the Mann–Whitney U test, and the differences in frequency between the 2 groups were compared using the Chi square test. The criterion for statistical significance was P < 0.05
