Univariate and multivariate adjusted^a analyses of the association between ChCA subtypes and recurrent ipsilateral hemorrhage in adult patients with MMD

ChCA Subtype	Presence of Recurrent Hemorrhage
	Univariate Analysis			Multivariate Analysis
	HR	95% CI	P Value	HR	95% CI	P Value
AChA anastomosis	1.77	0.71–4.41	.22	8.23	1.41–48.13	.02
MPChA anastomosis	2.14	0.86–5.29	.10	3.43	0.80–14.80	.10
LPChA anastomosis	6.66	2.18–20.39	<.01	5.78	1.58–21.13	<.01

^aMultivariate analysis was adjusted for confounding factors including age, sex, a history of ischemia, Suzuki stage >III, involvement of posterior cerebral arteries, thalamic anastomosis, fetal posterior communicating artery, and intracranial aneurysm.
