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
backgroundMagnetically controlled capsule endoscopy (MCCE) has recently increasingly been used for gastric examination. However, the image quality and esophageal observation is suboptimal. We developed a novel wired transmission magnetically controlled capsule endoscopy (WT-MCCE) system and evaluated its feasibility through in vitro and in vivo experiments.
methodsA plastic stomach model and a pathological upper gastrointestinal model were used to evaluate the performance of WT-MCCE in vitro experiments. Twice of examination in the two in vitro models by WT-MCCE were performed by 5 endoscopists who were experienced in performing wireless capsule endoscopy. The examination of traditional gastroscopy (Olympus, GIF-HQ290) in the pathological upper gastrointestinal model was set as the control. In vivo experiments were performed in a live canine model by 3 endoscopists, in which WT-MCCE was inserted with the assistance of gastroscopy. Measurements included maneuverability, examination time, visualization of gastric mucosa, image quality and diagnostic accuracy.
resultsWT-MCCE showed good performance in both in vitro and in vivo experiments with excellent visualization of mucosa (75-100%). The mean operation time is 17.6 ± 2.7 min, 22.3 ± 1.9 min and 29.3 ± 3.4 min in three models, respectively. In pathological upper gastrointestinal model, all lesions, including esophageal varices, one polyp, one foreign body, two gastric ulcers and one duodenal ulcer, were detected by both WT-MCCE and traditional gastroscopy by all endoscopists. For the observation of esophagus and stomach in the canine model, WT-MCCE also showed excellent maneuverability and good image quality.
conclusionsThe novel WT-MCCE system performed well in evaluating upper gastrointestinal landmarks and lesions in two in vitro models, and showed good performance in a canine model. WT-MCCE may be potentially useful for diagnosis of esophageal and gastric diseases.
