Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Change From Baseline in Hemoglobin (Hgb) at Week 24
Tijdsspanne: 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.

Tijdsspanne: Baseline; Week 24
Change from Baseline was calculated as the post-Baseline value minus the Baseline value.

All individual items were summed to create a single fatigue score ranging from 0 to 52. Higher scores indicate greater fatigue.
