Key result
Inviting men aged 64 to 83 years for abdominal aortic aneurysm screening had no significant effect on overall AAA mortality (rate ratio 0.91; 95% CI 0.68-1.21).

Inviting men aged 64 to 83 years for AAA screening via the electoral roll did not significantly reduce overall AAA mortality over a mean follow-up of 12.8 years.
McCaul et al. (2016) conducted an RCT in Abdominal aortic aneurysms (AAAs) (n=38,480). Invitation to undergo ultrasonography of the abdominal aorta vs. Control group without invitation was evaluated on Mortality from AAA (rate ratio 0.91, 95% CI 0.68-1.21). Inviting men aged 64 to 83 years for abdominal aortic aneurysm screening had no significant effect on overall AAA mortality (rate ratio 0.91; 95% CI 0.68-1.21).
