Univariate analysis of risk factors. Univariate analysis of risk factors for OS (A), CRFS (events include death, GF, and extensive or severe chronic GVHD) (B), modified GRFS (events include death from any cause, GF, acute GVHD grade III to IV, extensive, moderate/severe chronic GVHD, and secondary procedure) (C), acute GVHD grade III to IV (D), and extensive or moderate/severe chronic GVHD (E). The hazard ratio for donor type and serotherapy could not be assessed in this model for acute GVHD and chronic GVHD (panels D and E) because of too few events in at least one of the tested groups. BM, bone marrow; CB, cord blood; MMFD, mismatched family donor; MMUD, mismatched unrelated donor; MFD, matched family donor; MSD, matched sibling donor; MUD, matched unrelated donor; PB, peripheral blood; TT, thiotepa.
