HAMP and Sepsis: For each increase of 1 nmol/l of hepcidin upon admission the corresponding difference in peak serum creatinine level (defined as B) were neither significant in the sepsis group, B = 0.637 μmol/L (CI -0.489–1.764, p = 0.264) nor in the non-sepsis group, B = 0.133 μmol/L (CI -1.525–1.791, p = 0.873).
