Malignant melanoma of the anal canal: a case report.
Article in Journal of surgical case reports, 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
Anal melanoma is a rare and aggressive malignancy with early local invasion and high metastatic potential, leading to poor outcomes. Limited to case reports, the literature offers little guidance on standardized treatment. We report a case of a 71-year-old male with a year-long history of perianal pain and painful defecation, following decades of mild anal discomfort. He underwent hemorrhoidectomy for presumed hemorrhoids, but histopathology revealed invasive malignant melanoma. On presentation, per rectal exam showed perianal satellite nodules and black pigmentation of the anal canal. Imaging confirmed anal canal thickening with hepatic and pulmonary metastases. Given the advanced stage and positive margins, the patient was managed palliatively with systemic chemotherapy.
