Post-transplantation outcome of MDS patients receiving standard conditioning according to transfusion burden: probability of overall survival, (A) and non-relapse mortality, (B). Patients were categorized as receiving 20 or fewer, 20–40, or more than 40 PRBC units. The curves were estimated from multivariable Cox regression analysis adjusted for patients’ age and sex, WHO category, cytogenetics, disease status at transplant, presence of comorbidities, duration of transfusion dependency, source of stem cells and type of donor.
