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 Objectives: This study evaluated the clinical outcomes of a newly refined 8F stent introducer featuring an ultra-tapered metal tip and a preloaded, partially covered, self-expandable metal stent (PCSEMS) for one-step stent deployment during EUS-guided hepaticogastrostomy (EUS-HGS). Methods: A retrospective review of 34 patients who underwent EUS-HGS using the refined PCSEMS between February 2024 and February 2025 was conducted using a prospectively collected database. An expert and a novice endoscopist performed procedures. The primary outcome was technical success. Secondary outcomes included one-step deployment rate, adverse events, clinical success, recurrent biliary obstruction (RBO), and predictors of one-step stent deployment. Results: The technical success rate was 100%, with 88.2% of deployments being one-step. Adverse events occurred in 14.7%. Clinical success was 94.1%. RBO occurred in 12 patients (37.5%), with a median time to RBO of 115 days (95% confidence interval, 91 to not reached). Endoscopic reintervention was successful in 91.7% (11/12). Outcomes were comparable between the expert and novice, except for procedure time. A narrow needle-scope angle (≤138°) was associated with successful one-step deployment (86.7% Conclusion: The refined dedicated 8F stent introducer, featuring an ultra-tapered metal tip and preloaded with a PCSEMS for one-step EUS-HGS, achieved excellent technical and clinical success with an acceptable safety profile, although larger prospective studies are warranted.
