Fig. 5From: Predictive value of CAC score combined with clinical features for obstructive coronary heart disease on coronary computed tomography angiography: a machine learning methodThe decision curve analysis (DCA) of the three prediction models. Theoretically, all patients without obstructive coronary artery disease are represented by a black line, and all patients with obstructive coronary artery disease are represented by a gray line. The x-axis presented the Threshold probability. CACS model including CAC score only; The clinical model including atherosclerotic cardiovascular disease risk factors and CAC scoreBack to article page
