Targeted abdominal aortic aneurysm screening: a retrospective review of a high-volume Irish tertiary vascular centre.
Article in Irish journal of medical science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDespite modern surgical and resuscitative techniques, ruptured abdominal aortic aneurysms (AAA) carry a high mortality rate. Screening programmes aim to identify intact AAA in time for prophylactic repair. Ireland does not have a national screening programme for AAA. The Beaumont Hospital vascular unit serves as a tertiary referral centre for approximately one million people and runs an opportunistic AAA screening programme based on risk factors. One year of screening duplex were audited for AAA pick-up rate.Despite modern surgical and resuscitative techniques, ruptured abdominal aortic aneurysms (AAA) carry a high mortality rate. Screening programmes aim to identify intact AAA in time for prophylactic repair. Ireland does not have a national screening programme for AAA. The Beaumont Hospital vascular unit serves as a tertiary referral centre for approximately one million people and runs an opportunistic AAA screening programme based on risk factors. One year of screening duplex were audited for AAA pick-up rate.
methodsA retrospective audit of all AAA screening duplexes performed in the Beaumont Hospital Vascular Lab over a single year (January-December 2020) was performed. Indications for screening and outcomes were documented.
resultsOver 12 months, 198 screening duplex were performed. The majority of screened patients were male (64.6%, n=128) with a mean age of 72 years (+/- SD 10.64). Indications for screening included atherosclerotic disease (n=130, 65.6%), family history of AAA (n=23, 11.6%), suspected AAA on x-ray or bedside ultrasound (n=18, 9%) and eight were prompted by examination findings. Out of 198 duplexes, there was an AAA detection rate of 11.1% (n=22). Of the 22 AAAs confirmed on screening duplex, two (9%) were over threshold for surgical repair. Co-morbidities associated with AAA, there were 10 (45%) patients who were either active smokers or ex-smokers and 13 (59%) are hypertensive. At three-year follow-up, three patients have undergone elective EVAR and one has died of non-vascular causes.
conclusionOpportunistic screening for AAA in patients attending the vascular department based on atherosclerotic risk factors is a reasonable policy. Next steps should include a local cost-benefit analysis and developing formal departmental criteria for screening referral.
