The receiver operating characteristics (ROC) curve for the LM-LAD angle in the prediction of LAD stenosis.
The area under the curve (AUC) is 0.845. LM, left main coronary artery; LAD, left anterior descending coronary artery; CI, confidence interval.

The receiver operating characteristics (ROC) curve for the LAD-LCx angle in the prediction of LAD stenosis.
The area under the curve (AUC) is 0.659. LAD, left anterior descending coronary artery; LCX, left circumflex coronary artery; CI, confidence interval.
