Global Variations in Practices Concerning Roux-en-Y Gastric Bypass-an Online Survey of 651 Bariatric and Metabolic Surgeons with Cumulative Experience of 158,335 Procedures.
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 16 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
introductionThere is significant variation in practices concerning Roux-en-Y gastric bypass (RYGB) among bariatric surgeons, but there is currently a lack of robust data on the nature and extent of these variations. The purpose of this study was to understand global variations in practices concerning RYGB.
methodsA questionnaire-based survey on Survey Monkey® was created, and the link was shared freely on various social media platforms. The link was also distributed through a personnel email network of authors.
resultsA total of 657 surgeons from 65 countries completed the survey. Crohn's disease and liver cirrhosis were considered absolute contraindications for RYGB by 427 surgeons (64.98%) and 347 surgeons (53.30%), respectively. More than 68.5% of surgeons performed routine upper GI endoscopy while 64.17% performed routine ultrasound of abdomen preoperatively. The majority of surgeons (77.70%) used the perigastric technique for Gastric pouch creation. Approximately, 79.5% used orogastric bougie. More than 70% of the respondents did not use any staple line reinforcement routinely. Only 17.67% of surgeons measured the whole small bowel length, and the majority of surgeons (86.5%) used constant length of BP limb. Approximately, 89% used constant length of alimentary limb. Approximately, 95% of surgeons preferred antecolic bypass, and more than 86% routinely closed the Petersen defect. Marginal ulcer prophylaxis was used by the majority (91.17%). Almost 95% of surgeons recommended lifelong vitamin and mineral supplements.
conclusionThis survey identifies global variations in practices concerning RYGB. It identifies several areas for future research and consensus building.
