CI indicates confidence interval; GVHD, graft-versus-host disease.

*

The hazard ratio is for cord blood transplantation compared with bone marrow transplantation

Acute GVHD was evaluated in patients surviving 21 days or longer after transplantation with evidence of engraftment

Chronic GVHD disease was evaluated in patients surviving 100 days or longer after transplantation with engraftment
