Serum suPAR concentrations and predictive power for sepsis at ICU admission. (A) In patients with sepsis suPAR serum concentrations were significantly (P < 0.001, U-test) higher as compared with patients with non-septic etiology of critical illness. (B) Receiver operating characteristic (ROC) curve analyses comparing the diagnostic power in predicting sepsis of suPAR (black line, area under the curve = AUC 0.615) with classical markers of inflammation and bacterial infection, C-reactive protein (CRP; grey line, AUC 0.857), procalcitonin (PCT; dotted black line, AUC 0.780) and white blood cell count (leukocytes; dotted grey line, AUC 0.564).
