  1. aSHOCK: the septic shock cohort (systolic blood pressure < 90 mmHg after fluid challenge); SEPSIS: the sepsis without shock cohort; Control: emergency department patients without infection; StO2: tissue oxygen saturation; *Wilcoxon two-sample test; statistically significant using P = 0.017 with the Bonferroni correction. Data are means ± SD (medians).
