A new strategy for enteral nutrition using a deflection flexible visual gastric tube: A randomized crossover manikin trial.
Trial report in Medicine, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEnteral nutrition via gastric tube insertion is a routine clinical practice for critically ill patients, although complications due to blind manipulation are occasionally reported.
methodsAn 8.4Fr deflection flexible ureteroscope was delivered into a 15Fr conventional gastric tube to create a gastric visual guidance system. Twenty inexperienced physicians were randomly assigned to perform 5 repeated orogastric tube placements in a manikin using both the conventional method and the deflection visual gastric tube, for a total of 10 procedures per physician. Placement time, procedure-related complications, and participants' experience with both methods were recorded.
resultsUnder real-time guidance, the visual gastric tube successfully reached the stomach. The procedure provided additional information on the anatomy of the esophagus and stomach. Placement time was significantly less in the visual group than in the conventional group (39.39 ± 2.11 seconds vs 49.82 ± 3.11 seconds; P < .001). Procedure-related complications were not observed in the visual group; however, the gastric tube was misplaced into the airway in 19 out of 100 cases (19%) in the conventional group. Furthermore, 17 out of 20 participants (85%) preferred the visual gastric tube guide over the standard method.
conclusionsResults of this manikin model demonstrate that it is feasible to use the deflection flexible visual gastric tube to create a route for enteral nutrition and that such a procedure decreases placement time and procedure-related complications compared to the conventional procedure. These findings may point to a new strategy for gastric tube insertion in the future.
