ROC curve with SOFA score and other inflammatory biomarkers to predict patient mortality. The red line represents the reference; the blue line represents the lymphocyte count (AUC =0.346); the light green line represents the IL-6 concentration (AUC =0.765); the earthy green line represents the CRP concentration (AUC =0.536); the purple line represents the PCT concentration (AUC =0.537); and the yellow line represents the SOFA score (AUC =0.710). IL-6, interleukin-6; CRP, C-reactive protein; PCT, procalcitonin; SOFA, Sequential Organ Failure Assessment; ROC, receiver operating characteristic; AUC, area under the curve.
