Serum omentin-1 at enrollment (AUROC > 0.739) performed similarly with CRP (AUROC > 0.778), procalcitonin (AUROC > 0.707), IL-6 (AUROC > 0.69), IL-10 (AUROC > 0.678) and suPAR (AUROC > 0.64) in distinguishing sepsis from septic shock, as the comparison of the ROC curves did not yield any statistically significant results (p > 0.05 derived from the DeLong test) (Figure 3). This evidence concerns the gene IL6 and Sepsis.
