Figure 2. — ROC curves of PCT, NT-proBNP, IL-6, PT, TT, and SOFA score for predicting septic shock. Areas under the ROC curve are as follows: SOFA score (red line): 0.826 (95% confidence interval (CI), 0.760–0.892), P < 0.0001; PCT (blue line): 0.636 (95% CI, 0.541–0.732), P = 0.004; NT-proBNP (green line): 0.607 (95% CI, 0.515–0.699), P = 0.025; IL-6 (yellow line): 0.600 (95% CI, 0.507–0.694), P = 0.035; SOFA48h (sky blue line): 0.848 (95% CI, 0.786–0.910), P < 0.001; PT (gray line): 0.738 (95% CI, 0.657–0.816), P < 0.001; TT (yellow line): 0.600 (95% CI, 0.526–0.711), P = 0.13. ROC, receiver operating characteristic; PCT, procalcitonin; NT-proBNP, N-terminal brain natriuretic propeptide; IL-6, interleukin 6; PT, prothrombin time; TT, thrombin time; SOFA, Sequential Organ Failure Assessment score; SOFA48h, Sequential Organ Failure Assessment score at 48 hours.
