Prevalence of Previously Undiagnosed Abdominal Aortic Aneurysms in Patients with Intracranial Aneurysms: From the Brain and Aortic Aneurysms Study (BAAS).
Article in Neurocritical care, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundA relationship between intracranial and abdominal aortic aneurysms (AAA) has been appreciated through genome-wide association studies suggesting a shared pathophysiology. However, the actual prevalence of AAA in patients presenting with ruptured intracranial aneurysms is not known. Our aim was to estimate the prevalence of previously undiagnosed AAA in patients presenting with aneurysmal subarachnoid hemorrhage (aSAH) to see if it may be high enough to justify formally testing the utility of screening.
methodsA prospective, observational inception cohort study of 81 consecutive patients presenting to Mayo Clinic Florida with aSAH was performed from August 14, 2011 to February 10, 2014. These individuals were then screened using an abdominal ultrasound technique for an AAA. Our primary end point was detection of AAA. Our secondary end points were 30-day good-to-fair functional status (modified Rankin scale < 4) and all-cause mortality.
resultsWe detected an AAA in 10 patients (rate: 12%; 95% CI 6-22%) with aSAH. The mean diameter of these AAA was 3.4 ± 1.0 cm. Among these 10 patients, there was one death within the first month of aSAH hospitalization. There were no significant differences in demographic or clinical characteristics based on AAA detection status. Mean follow-up time was 4.7 years. The rate of good-to-fair functional status at 30-days was 79%. All-cause mortality during follow-up at 1-year was higher for patients with AAA (36%; 95% CI 0-61%) compared to patients without AAA (7%; 95% CI 1-14%) (log-rank p = 0.045).
conclusionsThe co-prevalence of AAA in patients presenting with ruptured brain aneurysms may be sufficiently high such that screening for AAA among likely survivors of aSAH might be appropriate. Larger studies would be needed to establish a net clinical benefit from screening AAA and then treating newly identified large AAAs in this morbid population.
