Low levels at baseline expressed as circulating MBL below 1300 ng/mL did not predict a future sepsis event (0.82 [0.55–1.23]), or increased severity; severe sepsis (0.94 [0.58–1.54]), septic shock (0.64 [0.32–1.27]), or hospital death (1.29 [0.54–3.08]). The gene discussed is MBL2; the disease is Sepsis.
