The serum MBL level in the septic shock group (1.85 μg/mL; IQR, 0.87 to 2.67) was higher (P < 0.05) than the severe sepsis (0.78 μg/mL; IQR, 0.39 to 1.37) or control groups (1.36 μg/mL; IQR, 0.39 to 2.74); however, the serum MBL level was not significantly different between the severe sepsis and control groups. This evidence concerns the gene MBL2 and Sepsis.
