Q3W = every three weeks; QW = weekly; EOTP = end of the treatment period (defined as the earlier of day 109 or end of study); Hb = hemoglobin; n = number of transfusion events. Note that as data described are for first transfusion only, n also equals the number of patients with at least one transfusion.
aThe closest hemoglobin value on the day of transfusion or within 7 days prior was used.
