CRP and alkaline phosphatase measurement: Receiver Operating Characteristic analyses showed a fair predictive accuracy of CRP within 24 h for mortality AUC: 0.741 (CI: 0.627–0.854) (Figure 2B) and poor predictive accuracy for both severe and mild AP, AUC: 0.690 (CI: 0.586-0.793) (Figure 2C) and AUC: 0.604 (CI: 0.554-0.653), respectively (Figure 2D).
