Accuracy data to predict CAD >50% and CAD >70% at CT angiography, when CFR-LAD or Agatston score were assessed as predictors. CAD = coronary artery disease, PPV = positive predictive value, NPP = negative predictive value, CFR-LAD = coronary flow reserve of the left anterior descending coronary artery
