A, The accuracy of coronary artery calcification (CAC) for prevalent coronary artery disease at baseline according to the Agatston and Weston scores was comparable using receiver-operating characteristic analyses: c-indices of 0.74 (95% CI, 0.70-0.79; P < .001) and 0.78 (95% CI, 0.74-0.82; P < .001), respectively. B, In those with COPD, the accuracy was comparable for the two scores: c-indices of 0.75 (95% CI, 0.70-0.80; P < .001) for the Agatston score and 0.76 (95% CI, 0.70-0.81; P < .001) for the Weston score.
