Sporadic ampullary adenoma mimicking adenocarcinoma in the absence of genetic predisposition: a case report.
Article in Journal of surgical case reports, 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
Ampullary tumors are uncommon and are frequently associated with hereditary cancer syndromes. Sporadic ampullary adenomas are infrequently reported and may mimic adenocarcinoma clinically and radiographically. We present a 71-year-old male with obstructive jaundice and imaging concerning for malignancy who was found to have a high-grade ampullary adenoma following attempted pancreaticoduodenectomy. Operative management required modification of the standard approach due to intraoperative anatomical distortions. This case highlights the diagnostic challenges in differentiating benign from malignant ampullary lesions and the implications for surgical management.
