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 authors present a case of bulbar ganglioglioma. Previously, there have only been 4 cases reported in the literature of surgery on a tumor originating in the medulla. OBSERVATIONS: A psychiatric patient presented with symptoms of intracranial hypertension. An MRI study showed a tumor near the fourth ventricle. Surgical intervention was performed, and complete resection and radiological cure were achieved. LESSONS: Tumors of the fourth ventricle, especially fibroelastic gangliogliomas, represent a complex surgical challenge due to their eloquent location and adhesions. Complete resection requires the use of microscopy and an ultrasonic aspirator. Treatment should be individualized, prioritizing maximum and safe resection, with close follow-up, while radiotherapy remains controversial and of limited indication. https://thejns.org/doi/10.3171/CASE25776.
