Cholangioscopy-assisted ERCP reduces radiation exposure in treating choledocholithiasis: a retrospective IPTW-adjusted cohort study.
Article in Frontiers in medicine, 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: Conventional ERCP for common bile duct stones relies on fluoroscopy, which raises concerns about radiation exposure and may not fully exclude residual stones. This study compared cholangioscopy-assisted ERCP with conventional fluoroscopy-guided ERCP in routine treatment of choledocholithiasis. Methods: This single-center retrospective study included 100 patients with bile duct stones treated between June 2024 and June 2025. The cholangioscopy-assisted group included patients who underwent electronic mother-baby cholangioscopy-assisted ERCP ( Results: Median radiation-dose reading was lower in the cholangioscopy-assisted group than in the conventional group (9.93 vs. 14.64 mGy, Conclusion: Cholangioscopy-assisted ERCP was associated with lower intra-procedural radiation-dose reading and fewer high-dose procedures in patients treated for choledocholithiasis. No statistically significant difference in short-term adverse events was observed, but longer procedure duration and higher cost were noted. These findings should be confirmed in prospective studies using standardized radiation metrics and longer follow-up.
