Resection of a ventrally located ossified thoracic spinal meningioma: illustrative case.
Article in Journal of neurosurgery. Case lessons, 2025. 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
backgroundResection of calcified meningiomas in the ventral thoracic spinal canal remains a formidable surgical challenge despite advances in technology and refined microsurgical techniques. These tumors, which account for a small percentage of spinal meningiomas, are characterized by their hardness, complicating safe resection and often resulting in worse outcomes than their noncalcified counterparts. OBSERVATIONS: The authors present the case of a 68-year-old woman with a ventrally located ossified meningioma at the T9-10 level, successfully treated via a posterolateral transpedicular approach. Additionally, they conducted a systematic review of the literature following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, focusing on the origins, imaging findings, surgical strategies, and outcomes of calcified meningiomas in the ventral thoracic spinal canal. Data were extracted and analyzed from 15 articles encompassing 18 cases. LESSONS: Calcified meningiomas in the ventral thoracic spinal canal require meticulous preoperative planning and a tailored surgical approach to optimize outcomes. The posterolateral transpedicular approach offers a balance between adequate exposure and minimizing spinal cord manipulation, making it a viable option for resecting these challenging tumors. A single facetectomy and pediculotomy do not compromise long-term spinal stability. Technological adjuncts, including ultrasonic aspiration, neuromonitoring, and endoscopic assistance, can further enhance surgical safety and effectiveness. https://thejns.org/doi/10.3171/CASE24603.
