Resolution of tonsillar herniation and syringomyelia after resection of supratentorial large meningioma.
Article in Brain & spine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: Chiari malformation type I (CM1) with syringomyelia caused by supratentorial lesions is extremely rare, and the mechanism has not been well explained. Methods: A 25-year-old female patient with no significant medical history who presented with progressive pain in the left neck for one month. MRI examination showed a giant meningioma in the trigone of the lateral ventricle accompanied with CM1 and syringomyelia. Results: The patient underwent left parietal-occipital cortical approach surgery to remove the giant tumor in the trigone of the left lateral ventricle. The neck pain and left upper limb numbness were relieved immediately. CM1 and syringomyelia disappeared without posterior fossa decompression after surgical resection of the supratentorial tumor. Conclusion: This case shows that supratentorial space-occupying lesions (SOLs) causing acquired Chiari malformation (ACM) and syringomyelia is closely related to the tumor oppresses and increases the pressure of the posterior cranial fossa. Posterior fossa decompression was not needed for ACM and syringomyelia.
