  1. AML acute myeloid leukemia, FluMel fludarabine/melphalan, BuCy busulfan/cyclophosphamide, FluTreo fludarabine/treosulfan, Dx diagnosis, HCT hematopoietc cell transplantation, CI comorbidity index, CR complete remission, MSD matched sibling donor, MUD matched unrelated donor, F to M female donor to male patient, CMV cytomegalovirus, BM bone marrow, PB peripheral blood, IQR interquartile range, min minimum, max maximum, neg negative, pos positive.
  2. p values for comparisons of continuous variables of FluMel or BuCy to FluTreo were calculated using the Mann–Whitney test. p values for comparisons of categorical variables were calculated by Pearson’s Chi Squared test.
