Figure 1. RBC and Platelet Transfusion Independence, All Patients.

Figure 1.

Panel A: Survival and Availability for Transfusion. By Day 101, 705 (88%) of n=800 subjects remained available for transfusion, and by Day 200, 623 (78%) remained available. Patients became unavailable for analysis upon: 1) death; or 2) censored due to a second transplant.

Panel B: RBC Transfusion Independence. About 25% of subjects attained RBC transfusion independence at Day 5, 50% at Day 15 and 75% at Day 44.

Panel C: Platelet Transfusion Independence. About 25% of subjects were platelet transfusion independent at Day 0, 50% at Day 9 and 75% at Day 14.

Data for Panels B and C are displayed on a modified Kaplan-Meier plot in which transfusion independence, defined as the day of last transfusion preceding 30 days during which no transfusion is needed, is the criterion for removing an individual from the graph. Earlier removal of a patient represents more rapid attainment of independence, and is thus more favorable. For patients who attained independence, if subsequent transfusions were needed, the interval until the next transfusion was >30 days.
