However, PCT values were not significantly higher in patients admitted to ICU in comparison with the others (9.6 [4.1–18.2] vs. 6.1 [3.9–14.1] μg/L, p = 0.145); same observation was done when comparing PCT values between patients with severe sepsis/septic shock versus others (8.6 [4.9–23.7] vs. 6.2 [3.6–12.3] μg/L, p = 0.064). This evidence concerns the gene CALCA and Sepsis.
