There were no significant associations between plasma levels of vitamin C and ferritin, transferrin, or iron (Additional file 1: Table S4), and vitamin C concentrations at baseline were not associated with WHO diagnosis, MDS prognostic risk category (IPSS-R score), blast percentage, haemoglobin level, or the number of blood transfusions, in this heterogeneous patient cohort (Additional file 1: Table S5A). This evidence concerns the gene TF and myelodysplastic syndrome.
