Association between coexisting atherosclerotic diseases and ipsilateral ACI

Coexisting intracranial artery stenosis ≥50% and	Presence of ipsilateral ACI
	Univariate regression			Multivariate regression*
	OR	95% CI	P value	OR	95% CI	P value
Carotid stenosis ≥50%	2.014	0.627 to 6.477	0.240	1.319	0.359 to 4.845	0.677
Carotid MWT ≥1 mm	5.043	2.378 to 10.694	<0.001	4.313	1.937 to 9.601	<0.001
Carotid calcification	3.864	1.723 to 8.664	0.001	3.606	1.513 to 8.593	0.004
Carotid LRNC	2.803	1.455 to 5.401	0.002	2.358	1.166 to 4.769	0.017
Carotid IPH	1.897	0.418 to 8.605	0.407	1.474	0.269 to 8.078	0.655
Carotid HRP	1.418	0.403 to 4.992	0.586	1.294	0.311 to 5.374	0.723

*Adjusted for confounding factors of age, gender, body mass index, hypertension, diastolic blood pressure, high-density lipoprotein, total cholesterol, smoking and diabetes. The regression analysis for coexisting intracranial artery stenosis ≥50% and carotid FCR (fibrous cap rupture) was not applicable due to very few cases.
ACI, acute cerebral infarct; HRP, high-risk plaque; IPH, intraplaque haemorrhage; LRNC, lipid-rich necrotic core; MWT, mean wall thickness.
