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

Background: Bilateral paramedian thalamic infarction due to occlusion of the artery of Percheron is a rare but clinically significant cerebrovascular event. Occlusion of the artery of Percheron may result in bilateral infarction, often presenting with altered mental status, vertical gaze palsy, and cognitive dysfunction. Case presentation: We present a case of a 67-year-old female with poorly controlled hypertension and diabetes who developed acute neurological symptoms. Initial CT imaging was unremarkable, but MRI confirmed bilateral paramedian thalamic infarction. Clinical discussion: Anatomical variations, such as the rare presence of the Percheron artery, can significantly alter the vascular architecture, leading to unique clinical syndromes when the artery is occluded. Conclusion: This report underscores the diagnostic challenges associated with Percheron syndrome. Treatment primarily involves supportive care, risk factor management, and rehabilitation.
