Frequency and Predictors of Ultrasound-Detected Extracranial Vertebral Artery Stenosis in a Sample of Non-Western Population.
Article in Australasian journal of ultrasound in medicine, 2025. 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
Objective: Extracranial vertebral artery (VA) stenosis represents an important aetiology of ischaemic vascular events in the posterior circulation. Nevertheless, it remains insufficiently investigated. Ethnic differences might be related to VA stenosis. In this regard, Egyptian studies are scarce. We aimed to investigate the frequency and predictors of extracranial VA stenosis in a sample of Egyptian patients. Methods: We enrolled consecutive patients who were referred to our neurovascular ultrasonography laboratory for routine clinical indications. Extracranial VA stenosis was diagnosed and graded using ultrasound. Results: We included 528 patients in our study. Significant extracranial VA stenosis ≥ 50% was found among 10.4% ( Conclusions: The frequency of extracranial VA stenosis seems to be lower among Egyptians in comparison with Western cohorts. Among patients with carotid atherosclerosis or significant CCA/ICA stenosis and/or ischaemic vascular events in the posterior circulation, meticulous ultrasound examination of the VA is warranted to detect possibly underlying extracranial VA stenosis.
