Next, the ROC curves (Fig 8B–8J) show that the ITGAM, CXCR2, and FCGR3B expression levels provide high accuracy for classifying the Sepsis and Control group (AUC > 0.9); MMP9, MPO, and CTSG expression levels exhibit moderate accuracy for this classification (0.7 < AUC < 0.9). Here, ITGAM is linked to Sepsis.
