Overall survival (Kaplan-Meier estimates) after allogeneic hematopoietic stem cell transplantation from genotypically HLA-identical siblings (ISDs), alternative (partially) HLA-matched family donors (MFDs), and HLA-matched unrelated donors (MUD). Results are given after stratification for early (ear) and advanced (adv) disease stage. ▵ indicates MFD ear (n = 48); •, MUD ear (n = 66); □, ISD ear (n = 110); ▴, ISD adv (n = 28); ▿, MUD adv (n = 35); and ⋄, MFD adv (n = 38).
