Fig. 1. The comparison of predictive values between DSE, TET, and DTS for prediction of CAS, and multi-vessel CAS in whole study population by ROC curve analysis. A: The comparison of ROC curves for prediction of CAS. B: The comparison of ROC curves for prediction of multi-vessel CAS. ^*p < 0.001 between TET and DSE, ^†p = 0.002 between DSE and DTS, ^‡p < 0.001 between TET and DSE, ^§p = 0.003 between DSE and DTS. DSE: dobutamine stress echocardiography, TET: treadmill exercise test, DTS: Duke treadmill score, CAS: coronary artery stenosis, ROC: receiver operating characteristic.
