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: Training in flexible gastrointestinal endoscopy is increasingly challenging. Simulation tools may help impart essential skills, but existing simulators lack real-time feedback, may be unrealistic, and are not aligned with recognized key performance indicators (KPIs). As a result, translating from simulator to real-world procedures has achieved variable outcomes. The Mikoto colonoscopy simulator (R Zero Inc, Tokyo, Japan) aims to address this gap by providing real-time feedback based on procedural dynamics, including patient comfort, producing a single performance-focused score (out of a maximum possible 100; the Mikoto Simulator Score [MSS]).We sought to establish construct and user validation for the MSS, with endoscopists' KPIs and structured user feedback. Methods: Twenty endoscopists of varying experience levels were recruited and categorized into novice, training, competent, and expert experience levels, based on lifetime colonoscopy numbers (national accreditation criteria). Participants provided their United Kingdom National Endoscopy Database (NED) KPIs before using the simulator. After standardized introduction and acclimatization, each then performed 3 full colonoscopies on the simulator, with the main test parameters being cecal intubation time and MSS. User validity was determined by means of a structured feedback questionnaire assessing utility and realism. Results: Significant differences were observed in median NED KPIs and MSS across all experience levels (n = 5 in each group, Conclusions: The Mikoto simulator demonstrates close alignment with NED KPIs for colonoscopy, with linear correlation in most cases, providing initial validation as an indicator of endoscopic competence in a nonpatient-contact setting. Further studies are warranted to assess integration into endoscopy training. The Mikoto simulator represents a promising tool for enhancing endoscopic training and improving patient outcomes.
