The types and durations of antiplatelet drugs for symptomatic vertebrobasilar artery stenosis: a retrospective study.
Article in Frontiers in neurology, 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
Background: Patients with symptomatic vertebrobasilar artery stenosis not only experience a first stroke event, but also have a high risk of recurrent stroke. Even though interventional techniques have been widely used in the treatment of cerebral infarction, the therapeutic efficacy for symptomatic vertebrobasilar artery stenosis patients are not superior to that achieved with simple drug therapy. However, the optimal choice of drugs and the duration of their use in a pure drug regimen remain unclear. Methods: This retrospective study analyzed data from Heyuan People's Hospital (2021-2023) on patients with vertebrobasilar artery stenosis. Patients were grouped by treatment duration (30/90 days ticagrelor vs. 90 days clopidogrel), all receiving aspirin. Outcomes included ischemic events, bleeding, and complications. SPSS version 22.0 was employed for statistical analysis. Results: This study included 217 patients with symptomatic vertebrobasilar artery stenosis. Clinical features and outcomes of efficacy and safety analyses were conducted. No significant differences in baseline data or safety outcomes were found. However, a significant difference in endpoint events was observed within 90 days for specific subgroups of symptomatic intracranial vertebrobasilar artery stenosis and CYP2C19 gene deletion. Conclusion: For patients with symptomatic vertebrobasilar artery stenosis, the ticagrelor plus aspirin regimen may provide an alternative therapeutic option to the aspirin plus clopidogrel bisulfate regimen. Furthermore, this regimen may represent a favored treatment choice for specific patient subpopulations.
