Association between Elevated Serum Tau Protein Level and Sepsis-Associated Encephalopathy in Patients with Severe Sepsis

Figure 3

The performance of the serum tau protein level-based analysis of the 28-day mortality among patients with severe sepsis, as evaluated by receiver operating characteristic (ROC). The optimal cutoff value of serum tau protein level of 75.92 pg/mL predicted the 28-day mortality with 81.1% sensitivity and 86.1%, specificity (AUC: 0.867, 95% CI: 0.789–0.945).
