DFS and OS probabilities. (A) The 2-year probabilities of DFS were 29% (95% CI, 21%-37%) and 36% (95% CI, 31%-41%) after HLA-haploidentical relative and HLA-matched unrelated donor transplantations, respectively. (B) The 2-year probabilities of OS were 46% (95% CI, 37%-54%) and 44% (95% CI, 39%-48%) after HLA-haploidentical relative and HLA-matched unrelated donor transplantations, respectively.
