Trial Outcomes & Findings for Data Acquisition for Optimization of Coronary Artery Disease (CAD) Algorithm (NCT NCT01564628)

NCT ID: NCT01564628

Last Updated: 2019-08-19

Results Overview

Cardiac noise marker (CAD-score) ability to separate CAD from non-CAD patients is estimated as the area under the receiver operating characteristic curve. The area under the receiver operating characteristic curve is plottet as sensitivity versus 1-specificity as a function of different CAD-score cut-off values. The area under the receiver operating characteristic curve is on a scale from 0-100%, the higher value means a better separation of CAD from non-CAD patients. CAD and non-CAD patients are defined by the CTA and CAG evaluations.
