Image Quality Parameter on cCTA − Group A	cCTA CAD⁻		cCTA CAD⁺		p Value
Image Quality Parameter on cCTA − Group A	n = 116		n = 272		p Value
Mean Calcification Score (0–3)	0.74	±0.67	1.81	±0.97	<0.001
Mean Artifact Score (0–3)	0.41	±0.62	0.90	±1.06	<0.001
Mean Opacification Score (0–3)	2.36	±0.75	2.18	±0.80	0.05
Mean Image Quality (0–3)	2.17	±0.74	1.69	±0.97	<0.001

Data are mean ± standard deviation. CAD⁻ = negative for significant coronary artery disease; CAD⁺ = positive for significant CAD.
