The aim of the study was to conduct a detailed analysis comparing the accuracy of common clinical findings, laboratory tests and DS in AC diagnosis. Patients and Methods: A cohort of 1,333 patients presenting with AAP were included in the study. The clinical history and diagnostic symptoms (n= 21), signs (n=14) and laboratory tests (n=3) were recorded in each patient. Results: The significant independent diagnostic predictors (disclosed by multivariate logistic regression model) were used to construct the DS formulas for AC diagnosis. These formulas were tested at five different cut-off levels to establish the most optimal diagnostic performance for clinically confirmed AC. In the ROC comparison test, there was no statistically significant difference in the AUC values of i) clinical history and symptoms (AUC=0.542), and ii) signs & laboratory tests (AUC=0.580), whereas both were significantly inferior (p=0.0001) to the AUC value of the DS (AUC=0.962). Conclusion: In the diagnosis of clinically confirmed AC, the DS formula is superior to clinical symptoms and signs, justifying the use of DS as an integral part of the diagnostic algorithm of AC in all patients presenting with AAP.
