Figure 2. MASS = Multicentre Aneurysm Screening Study; OR = odds ratio. *Age = standardized numbers were used for the Western
Australia trial because of an early age imbalance that was subsequently corrected . Meta-analysis of all-cause mortality in the abdominal aortic aneurysm screening trials.(24)

Appendix Figure 1. KQ = key question. KQ 1a = Does AAA screening, in an asymptomatic average-risk or high-risk population,
reduce AAA-related adverse health outcomes? KQ 1b = For individuals who do not have AAAs on initial screening, does periodic
repeated screening reduce AAA-related adverse health outcomes? KQ 2 = What are the harms associated with AAA screening? KQ
3 = For AAAs 3.0 to 5.4 cm detected through screening, does immediate repair or surveillance reduce AAA-related adverse health
outcomes? KQ 4 = What are the harms associated with repair of AAAs 5.5 cm or greater? KQ 5 = What are the harms associated
with immediate repair or surveillance of AAAs 3.0 to 5.4 cm? Primary care screening for abdominal aortic aneurysms (AAAs): analytic framework.
-
Appendix Figure 2. All abstracts were reviewed for relevance to other KQs. Articles from experts or reference lists were also
reviewed if relevant. Trial flow diagram of studies evaluated for inclusion in each key question (KQ).
