Receiver-operating characteristic (ROC) analysis of prognostic biomarkers. ROC curves for IL-10 (blue line), sCD25 (yellow line), IFN-γ (red line), procalcitonin (PCT) (green line) and Sequential Organ Failure Assessment (SOFA) score (orange line) values, observed in our patients stratified in nonsurvivors (n = 13) and survivors (n = 39) (used as controls for ROC analysis) either at the time of hospital admission (D-1) (A) or at the end of first week of hospital stay (D-7) (B).
