1 · What the graph read from it

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.

2 · The registry

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

backgroundThe optimal treatment approach for patients with severe atherosclerotic vertebral artery ostial stenosis (VAOS) is not yet supported by evidence from large-scale studies. Even with optimal medical treatment and effective risk factor management, substantial numbers of patients experience symptoms or recurrent strokes. Endovascular treatment is a potential solution, particularly when medicinal therapy alone is insufficient for symptom and stroke risk reduction. This study was aimed at assessing the safety and effectiveness of stent angioplasty in patients with VAOS.

methodsThis single-centre retrospective analysis included 564 procedures in 525 patients (symptomatic n=265, without recent symptoms n=260; 72.2% male; median age: 70 years; stenosis >75% n=371) who underwent stenting for atherosclerotic VAOS between 2008 and 2022. Vertebrobasilar tandem lesions and dissections were excluded. Digital subtraction angiography was performed in all patients during the follow-up. Patients' characteristics, periprocedural and postprocedural neurological events, and follow-up data were evaluated.

resultsStenting was successfully performed in all cases. The in-hospital stroke rate was 0.6% (disabling n=2; non-disabling n=1). No ipsilateral stroke or treatment-associated deaths occurred during a mean follow-up period of 56 months (min.-max., 9-183 months). In-stent restenosis >50% was found in 89 (15.8%) implanted stents, with the majority (70 out of 89) diagnosed within the first year, at a median time of 7 months.

conclusionsStent angioplasty was demonstrated to be a safe and feasible option for patients with VAOS, with a low risk of periprocedural stroke and symptom recurrence, and favourable stent patency rates at mid-term and long-term follow-up.
