Nonrelapse mortality. (A) The 2-year cumulative incidence of nonrelapse mortality after transplantation of grafts from haploidentical sibling (15%; 95% CI, 10-20) and HLA-matched sibling (13%; 95% CI, 10-15); P = .52. (B) The 2-year cumulative incidence of nonrelapse mortality after transplantation of grafts from offspring (21%; 95% CI, 15-27) and HLA-matched sibling (17%; 95% CI, 14-20); P = .025.
