Vascular and Hemorrhagic Events in Patients With Intracranial Arterial Stenosis After Ischemic Stroke, Who Were Either in Dual Antiplatelet Therapy or Single Antiplatelet Therapy

	Dual antiplatelet therapy	Single antiplatelet therapy	HR (95% CI)	P value
Vascular events	n=275	n=272
Any stroke	12 (4.4%)	27 (9.9%)	0.47 (0.24–0.93)	0.027
Ischemic stroke	11 (4.0%)	25 (9.2%)	0.47 (0.23–0.95)	0.031
Hemorrhagic stroke	1 (0.4%)	2 (0.7%)	0.55 (0.05–6.03)	0.620
Composite of stroke, myocardial infarction and vascular death	14 (5.1%)	31 (11.4%)	0.48 (0.26–0.90)	0.020
Hemorrhagic events	n=274	n=269
Any bleeding	12 (4.4%)	7 (2.6%)	1.83 (0.72–4.65)	0.20
Severe or life‐threatening bleeding	2 (0.7%)	3 (1.1%)	0.72 (0.12–4.30)	0.72

DAPT indicates dual antiplatelet therapy; HR, hazard ratio; and SAPT, single antiplatelet therapy.
