TFF2 and Sepsis: We found a higher risk of death risk in patients with serum SP levels < 339 pg/mL at the time of severe sepsis diagnosis than in patients with higher concentrations (Hazard Ratio = 3.5; 95% CI = 2.35–5.18; p < 0.001), in patients with serum SP levels < 203 pg/mL at day 4, and in patients with serum SP levels < 148 pg/mL at day 8.
