  1. CFB change from baseline, EOS end of study, EOT end of treatment, EQ-5D VAS, European Quality of Life 5 dimension questionnaire visual analog scale, FSS Fatigue Severity Scale, FU follow-up, n.s. not significant, SD standard deviation.
  2. **p < 0.01; ***p < 0.001.
  3. a“Worsened” was defined, using data from baseline and Week 24, as those patients with at least a Grade 1 change in anemia based on hemoglobin levels.
  4. b“Improved” was defined, using data from EOT and EOT + 24 weeks (EOS, 72 weeks), as at least a Grade 1 improvement in anemia based on hemoglobin levels.
