DFO, deferoxamine; DFP, deferiprone.
Data were analyzed using an ANCOVA model, with treatment as the main factor and covariates including overall average transfusional iron input during the study, baseline LIC, cardiac T2* MRI, or serum ferritin levels, as stratification factors. Unless otherwise stated, data are shown as LS mean (SE).
