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 ultrasound (EUS)-guided biliary drainage (BD) is becoming more common as a secondary drainage method in cases of difficult endoscopic retrograde cholangiopancreatography. In a recent study, EUS-BD reportedly demonstrated similar safety between elderly patients and all other patients. However, the appropriate stent for placement in elderly patients is unknown.

aimTo clarify whether a metallic stent (MS) or a plastic stent (PS) is suitable when performing EUS-BD in elderly patients.

methodsThis was a multicenter retrospective study of patients who underwent EUS-BD between March 2005 and February 2025. The data of patients aged 70 years or older who underwent successful EUS-BD were analyzed, and the long-term outcomes of patients treated with an MS (MS group) and those treated with a PS (PS group) were compared.

resultsNinety-four patients underwent successful EUS-BD, of whom 64 were aged 70 years or older. The PS group included 51 patients, and the MS group included 13 patients. The time to recurrent biliary obstruction (TRBO) was not significantly different between the PS group and the MS group (6-month recurrent biliary obstruction rate 50.8%

conclusionA PS might be sufficient for performing EUS-BD in elderly patients aged 70 years or older with benign biliary disease because it is easily replaced. However, an MS might be more effective for elderly individuals with malignant biliary obstruction because of the expectation of a longer TRBO and a reduced need for stent replacement.
