1 · What the graph read from it

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.

2 · The registry

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: Primary intraosseous meningiomas (PIM) are rare extradural tumors, representing less than 2% of all meningiomas. They are often slow-growing and may present with nonspecific radiological features, complicating diagnosis. Case Report: We report the case of a 48-year-old female with progressive left frontotemporal bulging over 12 months, without neurological deficits. Imaging revealed an osteoblastic lesion in the left sphenoid and temporal bones, causing mild compression of adjacent structures. The patient underwent craniectomy with complete tumor resection and immediate cranioplasty using a preplanned customized prosthesis. Histopathology and immunohistochemistry confirmed a meningothelial meningioma, with tumor cells confined to intertrabecular bone spaces and free surgical margins, consistent with a primary intraosseous origin. Postoperative follow-up demonstrated excellent cosmetic results and no recurrence. Conclusion: PIMs pose diagnostic and therapeutic challenges due to their rarity and nonspecific imaging features. Histopathology remains essential for definitive diagnosis. Preoperative 3D prototyping and customized prosthesis planning can optimize surgical reconstruction, reduce deformities, and improve cosmetic and functional outcomes. This case highlights the importance of integrating clinicoradiological evaluation, histopathology, and modern reconstructive techniques to achieve complete resection and minimize recurrence.
