Table 1 Baseline demographics, clinical variables, stress-echocardiography and computed tomography angiograms data in the entire population and in the subgroups with or without obstructive coronary artery disease > 50%

From: Equivocal tests after contrast stress-echocardiography compared with invasive coronary angiography or with CT angiography: CT calcium score in mildly positive tests may spare unnecessary coronary angiograms
