INVESTIGATIONS
Follow the claim to the evidence
Each investigation begins with a claim that is often presented as settled fact. We trace it to its original sources, examine what the evidence actually shows, and distinguish observed findings from inference, modelling and opinion.
We set out the potential benefits, harms, limitations and unanswered questions in plain language. The purpose is not to prescribe a conclusion, but to give readers the information needed to reach their own judgement.

How Common Is Death from a Ruptured Abdominal Aortic Aneurysm?

Can You Have AAA Screening After 65?
You can still request NHS AAA screening after 65 if you have not previously been screened. But is it better to have the scan at 65 or wait until 70 or 75? The evidence does not give a clear answer.
Why Is AAA Screening Offered at 65?
Why are men offered AAA screening at 65? The trials showed that screening can reduce AAA deaths, but they did not establish 65 as the best age to screen — and AAA is far less common today.
