Improving Operator Depth Vision in Gastrointestinal Endoscopy: A Pilot Study of a New Three-dimensional Imaging System.
Article in DEN open, 2026. 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
Background and aims: Traditional two-dimensional (2D) gastrointestinal endoscopy lacks depth perception, leading to potential diagnostic errors. This study evaluates a novel software-based three-dimensional (3D) endoscopy system that converts 2D images into 3D, compatible with existing endoscopes. Methods: A randomized comparative study was conducted with 32 endoscopists at NTT Medical Center. Participants were assigned to perform snaring tasks using either 2D or 3D imaging in short- and long-distance scenarios. Success rates in first attempts were compared between the two groups. Results: In the long-distance scenario, the first-attempt success rate was significantly higher in the 3D group (53.13%) compared to the 2D group (21.88%, Conclusions: The new 3D system enhances depth perception and distance judgment, particularly benefiting less experienced endoscopists.
