Adjusted estimates are to be interpreted as the expected outcome if the HLA-matched and HLA-mismatched groups were the same, on average, as the cord-blood group with respect to disease severity, age of the patient, year of transplantation, and presence or absence of minimal residual disease. The hazard ratio for death in the HLA-matched group versus the cord-blood group was 1.12 (95% CI, 0.77 to 1.63; P = 0.57), and the hazard ratio in the HLA-mismatched group versus the cord-blood group was 1.91 (95% CI, 1.23 to 2.98; P = 0.004). The hazard ratio for relapse in the HLA-matched group versus the cord-blood group was 1.95 (95% CI, 1.16 to 3.27; P = 0.01), and the hazard ratio in the HLA-mismatched group versus the cord-blood group was 1.97 (95% CI, 1.04 to 3.73; P = 0.04).
