At 48 h, hepcidin correlates, in mild AP, with SIRI at 48 h (r = 0.346, p <0.05) and CRP at 48 h (r = 0.536, p < 0.001) and in moderately severe AP, with NLR at 48 h (r = 0.690, p < 0.01), with no correlations with other biomarkers in severe AP. Here, HAMP is linked to alkaline phosphatase measurement.
