Odds ratios ^a of positive coronary artery and aortic calcium by smoking category in Japanese men aged 40–49

	Never smokers (N=57)	Smokers with lower pack-year (N=126)	Smokers with higher pack-year (N=130)	P
ORs of coronary calcification, [95% CI] CAC score ≥ 10	1.0	1.0, [0.2, 4.2]	2.9, [0.8, 11.3]	^¶
ORs ratios of aortic calcification, [95% CI]
AC score > 0	1.0	1.3, [0.6, 2.9]	4.1, [1.8, 9.4]	^¶
AC score ≥ 100	1.0	2.0, [0.4, 9.8]	10.4, [2.3, 47.1]	^¶

Odds ratios were calculated after adjusting for age, systolic blood pressure, high density lipoprotein cholesterol, low density lipoprotein cholesterol, body mass index, fasting glucose, and alcohol consumption.

ORs indicate odds ratios; CI, confidence interval; CAC, coronary artery calcium; AC, aortic calcium.

^¶

indicates P<0.05 between never smokers and smokers with higher pack-year.
