Target hemoglobin was defined as ≥ 11 g/dL during the treatment period in the absence of a red blood cell (RBC) transfusion on the day of measurement or during the preceding 28 days.

The time to target hemoglobin is the interval in weeks between study day 1 and the first day that a hemoglobin value ≥ 11.0 g/dL is observed during the treatment period. If a participant did not achieve the target hemoglobin by the time of withdrawal or the end of the treatment period (EOTP), the time to target hemoglobin was censored on the day of the last hemoglobin measurement or the EOTP, whichever was earlier. Median was calculated using Kaplan-Meier estimates.

Change in hemoglobin concentration from Baseline to the end of the treatment period (Week 16).

The number of participants with ≥ 1 red blood cell (RBC) transfusion from week 1 to end of study (EOS). Participants with a hemoglobin value ≤ 8 g/dL but no RBC transfusion were counted as having had a transfusion.

Number of participants with ≥ 1 RBC transfusion from Week 5 to end of study (Week 16)). Participants with a hemoglobin value ≤ 8 g/dL but no RBC transfusion were counted as having had a transfusion.

Number of participants with a hematopoietic response, defined as \> 2 g/dL increase from baseline or hemoglobin ≥ 12 g/dL during the treatment period in the absence of a red blood cell transfusion within the prior 28 days.

Number of participants with a hematopoietic response, defined as \> 2 g/dL increase from baseline or hemoglobin ≥ 12 g/dL during the treatment period in the absence of a red blood cell transfusion within the prior 28 days. Assessing the effect of iron in a factorial experiment.

The time to hematopoietic response is the interval in weeks between study day 1 and the first day that a hematopoietic response is observed during the treatment period. Hematopoietic response is defined as an increase in hemoglobin concentration of ≥ 2.0 g/dL from baseline or a hemoglobin concentration ≥ 12.0 g/dL in the absence of RBC transfusions on the day of measurement and during the preceding 28 days of the treatment period. If a participant did not achieve a hematopoietic response by the time of withdrawal or the end of the treatment period (EOTP), the time to hematopoietic response was censored on the day of the last hemoglobin measurement or the EOTP, whichever was earlier. Median was calculated using using Kaplan-Meier estimates.

Health related quality of life was measured using the Functional Assessment of Cancer Therapy (FACT) - Fatigue subscale. The FACT-F includes 13 fatigue items, with each item assessed on a 5-point scale (ie, response values of 0 to 4). The FACT-F subscale score ranges from 0 to 52, where a higher score represents less fatigue.
