Table 1. Demographic information and clinical risk factors for patients with ruptured and unruptured anterior communicating artery (ACoA) aneurysms.

	Unruptured	Ruptured	p value
N	37	42
Mean age (SD)	54.6 (13.1)	52.1 (11.9)	0.57
Female (%)	26 (70.3%)	24 (57.1%)	0.09
Hypertension (%)	17 (45.9%)	20 (47.6%)	0.48
Smoking (%)	11 (29.7)	24 (57.1)	0.05
Multiple aneurysms (%)	11 (29.7%)	5 (11.9%)	0.04
Family history (%)	4 (10.8%)	6 (14.3%)	0.79
Prior SAH (%)	2 (5.4%)	1 (2.4%)	0.45

P value indicates the level of statistical significance that the value of certain variable differs between the ruptured group and unruptured group (p<0.05 is considered statistically significant). SAH, subarachnoid hemorrhage.
