Recurrent Jejunal Melanoma Presenting as Obscure Gastrointestinal Bleeding: A Diagnostic Challenge.
Article in ACG case reports journal, 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
Melanoma commonly metastasizes to the gastrointestinal tract but is often asymptomatic. Symptomatic small intestinal metastatic melanoma presenting with overt gastrointestinal bleeding is uncommon and may be difficult to diagnose when the initial radiographic and endoscopic workup is unrevealing. We report a 47-year-old patient with prior stage III cutaneous melanoma status post wide local excision and sentinel lymph node biopsy, who declined adjuvant immunotherapy and surveillance, presenting with acute blood loss anemia occurring 3 years after definitive treatment. After nondiagnostic radiographic evaluation, esophagogastroduodenoscopy, colonoscopy, and push enteroscopy, anterograde double-balloon enteroscopy revealed an actively bleeding ulcerated midjejunal mass, later measuring 6 cm on surgical pathology, with pathology confirming the diagnosis of metastatic melanoma.
