Survival probabilities. (A) Leukemia-free survival according to conditioning regimen: 58% ± 5% in myeloablative conditioning (MAC) vs 63% ± 11% in reduced-intensity conditioning (RIC) at 2 years (P = .90). (B) Nonrelapse mortality according to conditioning regimen: 40% ± 5% in MAC vs 36% ± 11% in RIC at 2 years (P = .79). (C) Relapse incidence according to conditioning regimen: 18% ± 5% in MAC vs 26% ± 11% in RIC at 2 years (P = .27). (D) Overall survival according to conditioning regimen: 59% ± 5% in MAC vs 63% ± 11% in RIC at 2 years (P = .82). Solid curve indicates MAC; dashed curve, RIC; x-axis, years after transplantation; and y-axis, probability.
