HSP90AA1 and Sepsis: The AUC of HSP90α was 0.79 (95% CI [0.75–0.84], P < 0.001) with 88.67% sensitivity and 56.52% specificity in discriminating the patients with sepsis, which was weaker than SOFA score (AUC: 0.96, 95% CI [0.94–0.98], 79.33% sensitivity and 100% specificity) and superior than PCT (AUC: 0.70, 95% CI [0.64–0.76], 49.33% sensitivity and 76.36% specificity) (Fig. 2).
