Sex‐ and Race‐Stratified Hazard Ratios of Carotid Plaque for Atrial Fibrillation in the ARIC Study^a

Sex‐Stratified	Women		Men
	HR (95% CI)	P Value	HR (95% CI)	P Value
Model 1	1.47 (1.26–1.70)	<0.001	1.36 (1.19–1.56)	<0.001
Model 2	1.28 (1.10–1.50)	0.002	1.28 (1.12–1.47)	<0.001

Race‐Stratified	White		Black
	HR (95% CI)	P Value	HR (95% CI)	P Value
Model 1	1.52 (1.37–1.70)	<0.001	1.24 (0.96–1.60)	0.09
Model 2	1.33 (1.19–1.48)	<0.001	1.06 (0.81–1.38)	0.68

Model 1: Cox proportional hazard model adjusted for age and race. Model 2: model 1+adjusted for height, weight, systolic blood pressure, diastolic blood pressure, use of antihypertensive medication, current smoking, diabetes, history of heart failure, and history of myocardial infarction. P for sex interaction (model 2)=0.90, P for race interaction (model 2)=0.13. ARIC indicates Atherosclerosis Risk in Communities; HR, hazard ratio.

^aAnalysis was based on 13 796 participants.
