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

We report a case of syringomyelia in a 55-year-old man with a unique obstruction of Magendie's foramen. Spinal magnetic resonance imaging revealed a large syrinx extending from C1 to C3, with intermittent syringomyelia extending down to Th11. While the obstruction was not clearly evident on T2-weighted imaging, three-dimensional constructive interference in steady-state imaging demonstrated a thickened membranous tissue blocking the cerebrospinal fluid outlet, leading to syrinx formation. Surgical intervention, involving the resection of the thickened membrane to open the foramen of Magendie, resulted in considerable improvement in the syringomyelia and neurological symptoms. Histopathological examination revealed gliomesenchymal tissue, suggesting an embryonic origin of the obstruction. This case highlights the importance of detailed imaging, particularly three-dimensional constructive interference in steady-state sequence, in diagnosing foramen of Magendie obstruction and the potential for successful surgical treatment in selected cases. Histopathological examination is crucial for differentiating gliomesenchymal tissue from adhesive arachnoiditis.
