Cervicodorsal extramedullary intraspinal schwannoma: A case report and literature review.
Article in Surgical neurology international, 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
Background: Spinal schwannomas are benign nerve sheath tumors that typically arise in the intradural extramedullary compartment but may occasionally mimic intramedullary lesions on magnetic resonance imaging (MRI). Case Description: A 43-year-old female presented with progressive upper-limb numbness and weakness, thoracic pain, and dysphagia. MRI showed an apparently intramedullary cervicothoracic lesion, characterized by spinal cord expansion, heterogeneous signal, and absence of clear margins with the cord. The patient underwent C7-D2 laminectomy and complete microsurgical resection of a highly vascularized extramedullary tumor. Histopathology confirmed schwannoma, and postoperative evolution was favorable without new deficits. Conclusion: Cervicodorsal schwannomas can simulate intramedullary tumors, posing a diagnostic challenge. Complete microsurgical resection through a posterior approach provides excellent outcomes.
