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

backgroundEndoscopic biliary drainage for malignant hilar biliary obstruction (MHBO) remains a highly complex endoscopic retrograde cholangiopancreatography (ERCP) procedure. Each case requires an individualized approach, with outcomes influenced by the expertise of the medical center and access to advanced endoscopic tools.

aimTo compare different stent types and drainage strategies, including the use of adjunctive therapies, in patients with MHBO treated endoscopically.

methodsWe retrospectively analyzed 164 patients with MHBO (Bismuth types 3-4) who underwent exclusive endoscopic drainage. Patients were grouped by stent type-uncovered self-expandable metal stents (UCSEMS), bilateral plastic stents, or a mixed approach (fully covered self-expandable metal stents + plastic)-as well as by drainage strategy (unilateral/bilateral) and use of radiofrequency ablation (RFA) or chemotherapy.

resultsPatients receiving UCSEMS had significantly longer overall survival compared to those with plastic stents or the mixed approach (

conclusionBilateral UCSEMS stenting appears most effective for palliative treatment of MHBO. Adjunctive use of RFA and chemotherapy may further enhance survival, supporting a personalized, multidisciplinary approach.
