Independent Predictors of 30-day Mortality in Elective and Symptomatic AAAs

	OR	95% CI	P-value
Symptomatic aneurysm	2.14	1.3–3.3	.003
EVAR (vs. open)	0.40	0.2–0.7	.001
Age increase (by decade)	1.81	1.4–2.3	<.001
Female	1.83	1.2–2.8	.004
Dialysis dependent	8.28	3.2–21.2	<.001
Hx of severe COPD	1.85	1.2–2.8	.01
Juxtarenal aneurysm	1.68	0.99–2.9	.06

Initial model also included CHF episode within prior 30 days and elevated baseline creatinine >1.78mg/dl but not on dialysis Hosmer and Lemeshow test 0.52 (> 0.51 throughout all steps of model optimization)

EVAR repairs only: Symptomatic aneurysm OR 2.42 (CI 1.2–4.7, P=.01)

Open repairs only: Symptomatic aneurysm OR 1.83 (CI 0.9–3.9, P=.12)
