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

Vertebral artery ostium stenosis is a recognized risk factor for posterior circulation stroke, yet no standardized treatment guidelines exist. Endovascular stenting, particularly with balloon-expandable stents (BES), has emerged as a promising option. However, clinical data remain limited. An 85-year-old man presented with transient visual disturbances and was found to have multiple microinfarcts in the right occipital lobe and cerebellar hemisphere. Vascular imaging revealed severe right VA ostium stenosis with a contralateral PICA-ending VA. In the chronic phase, the patient underwent successful stenting of the right VA ostium using a Palmaz Genesis balloon-expandable stent via radial artery access. The procedure was uneventful, and follow-up MRI showed no new infarcts. The patient was discharged with no neurological deterioration (modified Rankin scale 1). Balloon-expandable stent placement at the vertebral artery ostium can be a safe and effective treatment option in selected patients with symptomatic vertebral artery ostium stenosis. Further studies are warranted to evaluate long-term outcomes and restenosis risk.
