The AUROC of albumin (ROC: 0.821; 95% CI: 0.782–0.860), NEWS (ROC: 0.768; 95% CI: 0.711–0.826), CCI (ROC: 0.794; 95% CI: 0.754–0.833), and SOFA (ROC: 0.837; 95% CI: 0.798–0.876) showed that albumin alone performs as good as or even better than the other multi-parametric scores for predicting 30-day mortality in patients with infection in the ED (Figure 2). Here, ALB is linked to infection.
