Clinical Impact of Piecemeal Resection Concerning the Lateral Spread of Ampullary Adenomas.
Article in Internal medicine (Tokyo, Japan), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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
Objective Endoscopic papillectomy (EP) has been recognized to be a safe and reliable treatment modality for ampullary adenomas. The purpose of this study was to determine the safety and efficacy of endoscopic piecemeal resection for laterally spreading ampullary adenomas and to compare these findings with a control population of smaller conventional ampullary tumors treated in the same time period. Methods Between May 1999 and September 2015, 136 patients underwent EP at Tokyo Medical University hospital. A total of 125 patients underwent en bloc resection, and 11 patients underwent piecemeal resection. Results The final pathological diagnoses were 103 adenomas, 14 carcinomas in adenomas, 4 carcinomas, and 4 hyperplasia in the en bloc resection group, versus 7 adenomas, 3 carcinomas in adenoma, and 1 carcinomas in the piecemeal resection group. A single treatment session was possible in 104 (83.2%) of the 125 patients in the en bloc resection group and in 8 (72.7%) of the 11 in the piecemeal resection group. The total resection rate including additional treatments was 98.4% in the en bloc resection group and 100% in the piecemeal resection group. Conclusion Piecemeal resection for laterally spreading ampullary adenomas was sufficiently performed compared with en bloc resection.
