Adjusted probability of leukemia-free and overall survival after bone marrow and cord-blood transplantation. The adjusted probability of 3-year survival without a recurrence of leukemia was 19% for recipients of mismatched marrow, 23% for recipients of cord blood, and 33% for recipients of HLA-matched marrow. Probabilities were adjusted for age, disease status at transplantation, and positivity for cytomegalovirus in the donor, recipient, or both.¹¹
