Figure 4. Receiver Operator Curve for Predicting Severe Sepsis/Septic Shock.

Figure 4

Only the first sample of day 2 was plotted. The severe sepsis/septic shock plasma angpt-2 levels (n=17) were compared to all others (n=23) on day 2 of illness. The area under the receiver operator curve was 0.77 (95% confidence interval, 0.61–0.93). The optimal cutoff for angpt-2 resulted in a 76% sensitivity, 74% specificity, 68% positive predictive value, and 81% negative predictive value for predicting severe sepsis or septic shock.
