What was measured

A mean hgb increase of ≥ 1.0 g/dL was analyzed as the percentage of participants with a hgb increase ≥ 1.0 g/dL compared with baseline (after applying the 14/3 day rule) that was sustained over any consecutive 56-day (8-week) period in the absence of RBC transfusions during the treatment period. (Week 1 through Week 24 and Week 1 through Week 48).
