Spinal malignant melanotic nerve sheath tumor with atypical magnetic resonance imaging findings: A case report.
Article in Surgical neurology international, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Malignant melanotic nerve sheath tumors (MMNSTs) are relatively rare, comprising <1% of all neoplastic peripheral nerve lesions. Here, we describe a 79-year-old male who presented with atypical magnetic resonance imaging (MRI) findings of an MMNST. Case Description: A 79-year-old male presented with lower back pain, paraparesis, and bladder/bowel dysfunction. The MRI showed an intradural extramedullary (IE) lesion at the T9-T10 level with low-signal intensity on T1-weighted images (WI) and high intensity on T2-WI, which markedly enhanced with contrast. The IE nerve root involved with the tumor was completely removed surgically. The lesion was confirmed to be an MMNST. In the absence of metastases, adjuvant therapy was deemed unnecessary. One year later, the lesion has not recurred. Conclusion: A 79-year-old male patient presented with a T9-T10 MR intradural lesion that was pathologically proved to be an MMNST, which was treated with gross total surgical resection (i.e., removal of the involved nerve root alone).
