Percutaneous Transluminal Angioplasty as Potentially Effective Treatment for Persistent Cognitive Decline due to Intracranial Carotid Artery Stenosis.

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: We describe a male patient with covert sustained cognitive impairment who underwent endovascular treatment for severe stenosis in the left intracranial internal carotid artery (ICA). Case Presentation: A 64-year-old man presented with transient dysarthria and dysphagia. Although he was alert, a cognitive evaluation revealed significant dysgraphia and a remarkable reduction in cognitive function. Diffusion-weighted imaging (DWI) revealed scattered high-intensity regions in the watershed area of the left cerebral hemisphere and severe stenosis in the C2 portion of the left ICA. Percutaneous transluminal angioplasty (PTA) was performed; a detailed examination revealed significantly improved cognitive function. One year later, the patient demonstrated further cognitive improvement, without any recurrent stroke. Conclusions: We consider that patients with severe intracranial stenosis, who have covert cognitive decline without apparent sustained symptoms, might be promising candidates for revascularization. Higher brain function in patients with severe intracranial arterial stenosis should be carefully screened because cognitive decline might not be evident at the time of initial presentation.
