Åtgärdsbeskrivning
Tidsram
Change From Baseline in Hemoglobin (Hgb) at Week 24
Tidsram: Baseline; Week 24
Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Estimates are from a mixed model of repeated measures (MMRM), including an intercept term and covariates for randomized treatment, visit, treatment by visit interaction, Baseline value, and Baseline value by visit interaction. The Kenward-Roger method was used along with an unstructured covariance matrix.

Tidsram: Baseline; Week 24
Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Participants were asked to respond to 13 statements (as they apply to the last 7 days) that other people with the same illness said are important with one of the following: 0, not at all; 1, a little bit; 2, somewhat; 3, quite a bit; 4, very much. All individual items were summed to create a single fatigue score ranging from 0 to 52. Higher scores indicate greater fatigue.
