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 AND

aimsEndoscopic biliary drainage for malignant biliary obstruction (MBO) in patients with surgically altered anatomy is challenging, and technical difficulty could differ by the anatomy. Balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) and endoscopic ultrasonography-guided biliary drainage (EUS-BD) are both emerging procedures, and we conducted the single-center, retrospective study to compare clinical outcomes of BE-ERCP and EUS-BD for MBO.

methodsConsecutive patients with surgically altered anatomy who underwent BE-ERCP or EUS-BD for MBO were retrospectively studies. Technical and clinical success rates, adverse events (AEs), and time to recurrent biliary obstruction (TRBO) were compared.

resultsPatient characteristics were comparable between BE-ERCP (n = 118) and EUS-BD (n = 32), other than more patients with hepaticojejunostomy in the BE-ERCP group (66% vs. 44%, P = 0.03). Technical success rate was significantly higher in the EUS-BD group (70% vs. 94%, P = 0.005), but clinical success rates (84% vs. 90%, P = 0.55), early AE (14% vs. 22%, P = 0.29) and late AE rates (42% vs. 38%, P = 0.84), and RBO rates (31% vs. 34%, P = 0.67) were comparable between the groups. TRBO was 170 and 206 days in the BE-ERCP and EUS-BD group (P = 0.37). In the subgroup analysis of patients with the intact papilla, the technical success rate of BE-ERCP was as low as 55%, compared to 94% in EUS-BD (P = 0.003).

conclusionEUS-BD was associated with higher technical success rate than BE-ERCP for MBO in patients with surgically altered anatomy.
