Clinical evaluation of a novel fluoroscopic mode for improving visibility during interventional endoscopic ultrasound (with video).

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: Interventional endoscopic ultrasound (I-EUS), including EUS-guided biliary drainage, is now widely performed, but it becomes challenging if the visibility of devices is inadequate. A novel visibility enhancement mode, termed "Accent mode," has recently become available for use with a fluoroscopic system. Objective: To compare the visibility of each device and pancreato-biliary ducts between Accent mode and Original mode during I-EUS. Design: A single-center non-randomized evaluation study. Methods: Patients who underwent I-EUS under Accent mode were prospectively enrolled. All evaluations were performed using recorded procedural videos. The visibility score was graded on a five-item scale, with evaluations performed by three experts and seven trainees. Results: Twenty patients (Accent group) and 24 patients (Original group) were enrolled. Mean guidewire visibility scores were significantly higher in the Accent group (4.95 and 4.95 in the expert and trainee observers, respectively) than in the Original group (2.53 and 2.32, respectively; Conclusion: In conclusion, Accent mode appears to reduce I-EUS procedure time. It is necessary to confirm these findings in a prospective, randomized, controlled trial.
