CnI indicates calcineurin inhibitor; DRI, disease risk index (see text); HR, hazard ratio; MAC, myeloablative conditioning; MMF, mycophenolate mofetil; MRD, matched related donor; MTX, methotrexate; MUD, matched unrelated donor; N/A, not applicable; OS, overall survival; PB, peripheral blood; PFS, progression-free survival; RIC, reduced-intensity conditioning; Siro, sirolimus; TCD, T-cell depletion; and UCB, umbilical cord blood.

^*OS and PFS models are stratified on conditioning intensity, graft source (BM vs PB), and year of transplantation (2000-2001, 2002-2004, 2005-2009), so no HRs or P values are provided for those variables.
