HAMP and chronic kidney disease: The association between erythroferrone and mortality risk was analysed using Fine-Gray analysis, accounting for kidney transplantation as a competing risk.<h4>Results</h4>Erythroferrone, hepcidin and ferritin were higher in PD patients and in CKD 5 patients as compared with CKD 3-4 patients, whereas the hepcidin-to-ferritin ratio did not differ between the cohorts.
