**Semantic type:** Finding

**Definition:** Minor hematologic improvement-erythroid response in high transfusion burden patients is defined as a reduction by at least 50% of RBCs over a minimum of 8 weeks with the same transfusion policy (defined in "1.2.4. Transfusion policy") compared with 16 weeks prior to treatment. Only a response duration of at least 16 weeks, however, is considered clinically meaningful.
