Plasma 5-HIAA levels in patients with septic infection. Plasma 5-HIAA levels among healthy controls, sepsis patients without septic shock, and sepsis patients with septic shock were determined by the Kruskal–Wallis test and Steel–Dwass test for post-hoc analysis. *p < 0.05, **p < 0.01 by Steel–Dwass test.
