Key result
Current cigarette smoking in older adults was associated with a higher prevalence of clinically significant internal carotid stenosis compared to never-smokers (9.5% vs 4.4%, P<0.0001).

Absolute Event Rate: 9.5% vs 4.4%
p-value: p=< .0001
Cigarette smoking exhibits a significant, dose-dependent association with increased carotid artery wall thickness and stenosis in older adults.
Tell et al. (1994) conducted a cross-sectional in carotid artery atherosclerotic disease (n=5,116). Cigarette smoking vs. Never-smokers was evaluated on Clinically significant (>= 50%) internal carotid stenosis (p=< .0001). Current cigarette smoking in older adults was associated with a higher prevalence of clinically significant internal carotid stenosis compared to never-smokers (9.5% vs 4.4%, P<0.0001).
