The baseline characteristics of healthy participants and patients recruited. The septic shock cohort is a subset of the patients with severe sepsis. The values have been calculated using healthy, sepsis, and severe sepsis participant cohorts where appropriate. values represented by are from a Kruskal-Wallis test, # from a Fisher’s exact test, Φ from a χ2 test, and from a Mann–Whitney U test.
