Primary pulmonary meningioma: a case report and literature review.
Article in International journal of surgery case reports, 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
Introduction and importance: We report the case of a 40-year-old asymptomatic woman with incidentally detected primary pulmonary meningioma (PPM), underscoring its relevance in the differential diagnosis of solitary pulmonary nodules. Case presentation: A 40-year-old asymptomatic woman was found to have a left subpleural pulmonary nodule (11 × 9 × 8 mm) on routine follow-up imaging. Computed tomography findings and a preoperative needle biopsy suggested a diagnosis of meningioma. Video-assisted thoracoscopic resection of the left lower lobe was performed, and histopathological examination confirmed PPM. The postoperative course was uneventful, and no recurrence or metastasis was observed during follow-up. Clinical discussion: Given the tumor's location and histological appearance, alternative diagnoses - including inflammatory myofibroblastic tumor - were excluded through immunohistochemical analysis. Surgical resection remains the definitive treatment for PPM, whereas the benefit of adjuvant therapy is unclear due to limited available evidence. Conclusion: PPM usually presents as an asymptomatic, solitary, or occasionally multiple, well-circumscribed pulmonary nodule. Needle biopsy alone may result in misdiagnosis due to sampling limitations. Definitive diagnosis requires a combination of immunohistochemical analysis (e.g., SSTR2) and evaluation of the complete surgical specimen.
