Anomalous hemorrhage in myxopapillar ependymoma: illustrative case.
Article in Journal of neurosurgery. Case lessons, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis is the case of a 22-year old male with bilateral leg pain caused by an intradural lesion at the L3 level. On MRI, there were no signs of hemorrhage. Resection was performed and a raspberry-like lesion with attached veins was identified. Histopathological analysis showed a myxopapillary ependymoma. OBSERVATIONS: Although hemorrhage is rare, myxopapillary ependymomas are highly vascularized and carry the highest risk of intratumoral bleeding among spinal ependymomas. In the literature, most patients with hemorrhage of myxopapillary ependymomas present with neurological deterioration. Rarely are these patients noted to be clinically stable. LESSONS: Despite no worsening of symptoms or preoperative evidence of hemorrhage, intraoperative findings revealed a hemorrhagic lesion attached to vascular structures and potentially the filum terminale. Hemorrhage in a myxopapillary ependymoma without clinical deterioration is a rare occurrence. https://thejns.org/doi/10.3171/CASE25791.
