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: Interdural spinal meningiomas, arising between dural layers, are exceptionally rare. Case Description: A 50-year-old male presented with a 2-month history of lower back pain and numbness in the left L2-L3 dermatome. The magnetic resonance imaging (MRI) demonstrated a 25 × 14 × 8 mm, well-circumscribed, extradural-appearing mass at L2 with extension into the left L2/3 foramen. The lesion was hypointense on the T2WI and T2 heterogeneously enhanced with gadolinium. The preoperative differential diagnosis included schwannoma and extradural meningioma. At surgery, the lesion was entirely interdural. Complete resection was achieved with preservation of the inner dural layer. Histopathological examination confirmed a metaplastic meningioma with extensive chondroid metaplasia. The patient's symptoms resolved completely, and at 7 postoperative months, the MRI showed no recurrence. Conclusion: Here, we report an interdural L2-L3 meningioma that was completely resected while preserving the inner dural layer.
