Article in Therapeutic advances in gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06933576 (Contribution of the EyeMAX™ 11Fr), which is not on this map. Cited by 2 papers.
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.

Abstract
Background: Digital single-operator cholangioscopy (DSOC) enhances biliary stricture diagnosis, but the collection of quality samples can be difficult due to the small diameter of the working channel. Objectives: A new DSOC system (EyeMAX™ 11Fr; Micro-Tech Endoscopy, Nanjing, China) with a 2.0-mm working channel, accommodating pediatric forceps (1.6 mm), has been introduced in France. This study reports on the first French experience. Design: A retrospective, multicenter observational study. Methods: The study on DSOC was conducted across five endoscopy units within the French Society of Private Hepato-Gastroenterology (SFHGL-CREGG). Satisfaction and procedural evaluations were recorded using a visual analog scale (VAS) and compared with the Spyglass™ DS II (Boston Scientific, Marlborough, MA, USA). Results: Among 28 patients, 71.5% had undergone prior endoscopic sphincterotomy. Indications were biliary strictures in 26 patients and lithiasis in 2. Strictures were located in the bile duct (41%) or hilum (59%). The mean satisfaction score was 8.69 out of 10, with the EyeMAX 11Fr rated as superior to the SpyGlass DS II in 86% of cases. The mean biopsy count was 8.52 in 13.19 min, with 100% procedural success. Pathology specimens were rich (24%), adequate (52%), low (12%), or absent (12%). Sensitivity for cholangiocarcinoma was 73.7% (14/19). Benign strictures regressed in all cases. Procedure-related complications included pain twice (7.1%), fever once (3.6%), infection once (3.6%), and pancreatitis twice (7.1%), all of which were resolved rapidly. Conclusion: This first study on the EyeMAX 11Fr DSOC highlights its ease of use, superior biopsy facilitation, and high user satisfaction, achieving 73.7% sensitivity for cholangiocarcinoma diagnosis. Trial registration: ClinicalTrials.gov ID: NCT06933576.
