Establishment of animal model of gastroesophageal reflux disease by per-oral endoscopic tunneling: a preliminary study.
Article in Journal of thoracic disease, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAlthough a variety of antireflux procedures and medications are used to treat gastroesophageal reflux disease (GERD), reliable large-animal models of GERD that can be used to objectively compare the efficacy of these treatments are lacking. We developed a method to establish large animal models of GERD by endoscopic sphincterotomy to develop an endoscopic treatment for GERD.
methodsIn this study six flesh swine carcasses were used. A full thickness incision was made at the esophageal site 5 cm above the dentate line by per-oral endoscopic tunneling. Esophageal radiography was conducted before and after surgery to observe changes at the site of the lower esophagus 5 cm above the dentate line and in the cardia.
resultsThere was no significant change in the diameter of the esophageal site 5 cm above the dentate line before and after surgery, while the cardiac orifice significantly relaxed after surgery and enabled the contrast agent to smoothly travel through. The difference in diameter was statistically significant (P<0.05).
conclusionsOur experiments showed that it is a minimally invasive and mature technology of establishing GERD animal models by using the per-oral endoscopic tunneling technique, and might be a new method to establishing GERD large animal models.
