  1. Data are % (raw data) [95% confidence interval] for accuracy, sensitivity, specificity, PPV, and NPV; Data are value [95% confidence interval] for AUC
  2. CCTA = coronary CT angiography; DE-CTP = dual-energy CT perfusion; PPV = positive predictive value; NPV = negative predictive value; AUC = area under the receiver operating characteristic curve
