The predictive ROC curve of PASS score, IL-6, PCT and WBC in AP showed that the AUCs of PASS score, IL-6, PCT and WBC in predicting AP were 0.916, 0.819, 0.959 and 0.749, respectively, suggesting that PCT had the highest diagnostic efficacy, followed by PASS score and IL-6, while WBC had the lowest efficacy (Table-IV, Fig.1). The gene discussed is IL6; the disease is alkaline phosphatase measurement.
