The median PCT value was 0.13 μg/L (IQR: 0.07–0.50 μg/L) and PCT was significantly higher in the patients with sepsis (1.17 μg/L; IQR: 0.25–5.10 μg/L) than in those without sepsis (0.10 μg/L; IQR: 0.06–0.20 μg/L; p < 0.0001) (Supplementary Figure S2). This evidence concerns the gene CALCA and Sepsis.
