Multivariate exploratory analysis showed no association between the primary endpoint of the study (time to initiation of other anemia management or occurrence of Hb trigger) with hepcidin level at baseline (HR 0.92; 95% CI 0.73, 1.16; p = 0.49), the change in hepcidin from baseline to week 8 (HR 0.96; 95% CI 0.83, 1.11; p = 0.56) or the change to week 24 (HR 1.22; 95% CI 0.88, 1.68; p = 0.24) as covariates. Here, HAMP is linked to anemia.
