Spontaneous bilateral vertebral artery dissection complicated by hemodynamic posterior circulation stroke: A case report.
Article in Radiology case reports, 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
Bilateral vertebral artery dissections account for only 8% of all vertebral artery dissections and cause just 2% of all ischemic strokes. They can occur spontaneously, even without any triggering factor. Classical clinical findings, such as headache or neck pain, may be absent, particularly in the context of a stroke. Imaging is the modality of choice for diagnosis and includes ultrasound, catheter-based DSA, computed tomography angiography, and MRA. The main differential diagnoses include atherosclerotic plaques, hypoplastic vertebral artery, and vertebral artery fenestration. The primary treatment involves antithrombotic therapy. We report the case of a 57-year-old woman with no history of cardiovascular disease who presented to the emergency department with hemibody weakness and slurred speech. Magnetic resonance imaging on admission revealed multiple hypoperfusion-related ischemic areas involving the vertebrobasilar artery territory and findings suggestive of bilateral vertebral artery dissection.
