Prevalence of Endoscopic Findings Before Bariatric Surgery and Their Influence on the Selection of the Surgical Technique.
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeRoux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the two most popular procedures performed. The decision of which technique is most appropriate depends on the surgeon's preferences and experience. However, several factors strongly influence the decision of the procedure performed, including gastrointestinal disorders or asymptomatic upper gastrointestinal endoscopy (UGE) findings. This study aimed to describe the pathological endoscopic findings in morbidly obese patients undergoing preoperative routine UGE. MATERIALS AND
methodsA retrospective review of a prospectively collected database of all UGEs performed before bariatric surgery was performed. UGE was routinely performed to all the patients as part of the preoperative evaluation protocol.
resultsA total of 790 patients were included. Surgical technique included 610 (77.2%) RYGB and 180 (22.8%) SG. Twenty-one asymptomatic patients presented esophagitis at UGE. In only seven patients (0.89%), the endoscopic findings of esophagitis had changed the initial surgical decision. The presence of ulcers or adenomatous or incompletely resected polyps was an indication for SG, to assure future endoscopic access in case it is needed. In 25 patients (3.17%), the initial operation would have been changed based on UGE findings.
conclusionPreoperative UGE allows the diagnosis of asymptomatic esophagitis related to gastroesophageal reflux disease and the identification of asymptomatic polyps and ulcers, with the potential ability for malignant transformation. In up to 3.17% of the cases, the endoscopic findings changed the operative strategy. As the complication rate associated with the procedure is low, we recommend the routine performance of preoperative UGE before bariatric surgery.
