1 · What the graph read from it

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.

2 · The registry

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: Endoscopic nasobiliary drainage (ENBD) conversion to internal drainage using scissor forceps is a specialized technique primarily explored in malignant obstructions. This study evaluates its efficacy, radiation safety, and long-term durability in patients with benign biliary obstruction (BBO) compared to conventional endoscopic retrograde biliary drainage (ERBD). Objectives: To evaluate the efficacy, radiation safety, and long-term durability of scissor forceps conversion compared to conventional endoscopic retrograde biliary drainage (ERBD) in patients with BBO. Design: A retrospective comparative study using 1:1 propensity score matching (PSM). Methods: We retrospectively analyzed BBO patients who underwent either scissor forceps conversion (Experimental group) or conventional ERBD (Control group) between 2018 and 2025. To ensure rigorous comparison, 1:1 propensity score matching (PSM) was performed, balancing baseline characteristics including age, etiology, and inflammatory markers. Primary endpoints were dose area product (DAP), fluoroscopy time, and long-term stent patency. Results: After 1:1 matching ( Conclusion: In BBO management, converting ENBD to internal drainage significantly enhances radiation safety and procedural efficiency without compromising clinical safety or long-term stent durability. This "mini-invasive" approach aligns with the ALARA principle and represents a refined evidence-based strategy for patients requiring cumulative biliary interventions.
