Development of ulcer disease after Roux-en-Y gastric bypass, incidence, risk factors, and patient presentation: a systematic review.
Synthesis in Obesity surgery, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 90 papers, 9 of them syntheses 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.

Abstract
Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the gold standard in bariatric surgery. A long-term complication can be marginal ulceration (MU) at the gastrojejunostomy. The mechanism of development is unclear and symptoms vary. Management and prevention is a continuous subject of debate. The aim was to assess the incidence, mechanism, symptoms, and management of MU after LRYGB by means of a systematic review. Forty-one studies with a total of 16,987 patients were included, 787 (4.6%) developed MU. The incidence of MU varied between 0.6 and 25%. The position and size of the pouch, smoking, and nonsteroidal inflammatory drugs usage are associated with the formation of MU. In most cases, MU is adequately treated with proton pump inhibitors, sometimes reoperation is required. Laparoscopic approach is safe and effective.
