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

Distal malignant biliary obstruction (dMBO) is a common complication of advanced malignancies, particularly pancreatic cancer and biliary tract cancer, requiring biliary drainage to relieve symptoms. Endoscopic drainage using self-expandable metal stents (SEMS) is widely preferred due to improved long-term patency compared with plastic stents. However, the choice between fully covered SEMS (FCSEMS) and uncovered SEMS (UCSEMS) remains controversial, primarily due to migration risks associated with FCSEMS. Recent advances in stent design, such as anchoring flaps, flared ends, and anti-migration coatings, have been developed to improve FCSEMS stability. Additionally, techniques incorporating double-pigtail plastic stents as internal or external anchors have demonstrated significant reductions in migration rates. This review examines the current literature and evaluates various anti-migration strategies for FCSEMS, highlighting the clinical efficacy and challenges associated with each approach. Understanding these innovations is crucial for optimizing stent selection and improving patient outcomes in dMBO.
