Ehlers and colleagues conclude from their long term modelling study that screening men aged 65 for abdominal aortic aneurysm is not cost effective.1 This conclusion conflicts with that of the 10 year follow-up of the randomised Multicentre Aneurysm Screening Study (MASS),2 our detailed long term modelling based on individual patient data in MASS,3 4 and other recent modelling studies.
