LFS indicates leukemia-free survival; RI, relapse incidence; NRM, nonrelapse mortality; CMV, cytomegalovirus; WBC, white blood cell count; CR, complete remission; Ph+, Philadelphia chromosome–positive; ATG, antithymocyte globulin; ALG, antilymphocyte globulin; and TBI, total body irradiation.
Statistically significant.
