Extrahepatic hepcidin production: The intriguing outcomes of recent years

Figure 1 Hepcidin signals measured by liquid chromatography tandem mass spectrometry in cerebrospinal fluid of patients with bacterial meningitis and viral meningitis (n = 5 per group). Hepcidin signal is expressed in arbitrary unit, corresponding to the ratio of the area under the curve of hepcidin signal on the area under the curve of internal standard (heavy hepcidin). According to the Mann-Whitney test the difference was significant (P = 0.0076).
