We analyzed a cohort of intra-abdominal origin septic patients (n = 35, Supplementary Table 1), who presented elevated levels of C-reactive protein (CRP) and procalcitonin (PCT) in their plasma 24 h after sepsis initiation, when compared to a control group of abdominal surgery patients that had not developed sepsis (Fig. 1a). Here, CRP is linked to Sepsis.
