Presepsin as a biomarker for risk stratification for acute cholangitis in emergency department: A single-center study

Figure 3 Receiver operating characteristic curves for white blood cells, C-reactive protein, procalcitonin, presepsin, and total bilirubin for classification of severity and prediction of positive blood culture in acute cholangitis. The Delong test was used to compute the P value for comparison of the area under the receiver operating characteristic curve. A: Mild acute cholangitis vs moderate acute cholangitis; B: Moderate acute cholangitis vs severe acute cholangitis; C: Positive blood culture in acute cholangitis. P < 0.05 was set as the significant level. WBC: White blood cell; CRP: C-reactive protein; PCT: Procalcitonin; PSP: Presepsin; T-Bil: Total bilirubin; AUC: Area under the receiver operating characteristic curve.
