Figure 1

ROC curves for urine sTREM-1 and APACHEII for distinguishing sepsis from SIRS. Area under the curve (AUC) turned out respectively as urine sTREM-1 0.797 (95% CI 0.711 to 0.884) and APACHE II score 0.722 (95% CI 0.586 to 0.858). Using a cut-off point for urine sTREM-1 of 34.2 pg/ml, the sensitivity was 0.643, the specificity was 0.938, Positive Predictive Value (PPV) was 0.983, Negative Predictive Value (NPV) was 0.198 and Youden index (YI) was 0.581. Using a cut-off point for APACHE II score of 13.5, the sensitivity was 0.714, the specificity was 0.625, PPV was 0.913, NPV was 0.197 and YI was 0.339.
