Predictors of death after one year.

Risk factors	Odds ratio	95% Confidence interval	p
Sex	0.89	0.35–2.27	0.80
Age	1.09	1,049–1,141	<0.0001
WFNS Grade	3.23	1.89–5.53	<0.0001
Early cerebral ischemia	1.73	0.63–4.77	0.29
Delayed cerebral ischemia	0.76	0.26–2.27	0.62
Hypertension	0.12	0.041–0.33	<0.0001
Diabetes mellitus	1.07	0.32–3.61	0.92
History of smoking	0.31	0.098–0.99	0.048
Hypercholesterolemia	0.77	0.22–2.68	0.69

Binary logistic regression was performed with dichotomized status of death (0 = “alive”; 1 = “dead”) as the dependent variable and sex, age, WFNS grade, ECI, DCI, hypertension, diabetes mellitus, smoking history, hypercholesterolemia and hypothyreosis as independent variables.
