Min HK, et al. - Researchers used multivariate linear regression analysis to examine the link between hepcidin, iron indices and bone mineral metabolism in non-dialysis chronic kidney disease (CKD) patients. They analyzed data for 2238 patients from a large-scale multicenter prospective Korean study (2011–16) and excluded 214 patients with missing data on markers and related medications of iron and bone mineral metabolism, hemoglobin, blood pressure and causes of CKD. Findings demonstrated a close correlation between markers of bone mineral metabolism and iron status, including hepcidin.
