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 trisectoral metal stent (MS) placement for malignant hilar biliary obstruction (MHBO) poses technical challenges, although it may prolong survival and stent patency. Combined stent-by-stent and stent-in-stent (SBSIS) methods can reduce technical difficulty. This study aimed to examine the use of the SBSIS in patients with Bismuth type III or IV MHBO.

methodsThis prospective pilot study enrolled 30 eligible patients between January 2020 and October 2022. The study outcomes included technical and clinical success, recurrent biliary obstruction (RBO), and adverse events (AE) besides RBO associated with SBSIS for MHBO.

resultsThe technical success rate was 93.3% (28/30 patients). Clinical success was achieved in all patients with technical success. The early and late AEs rates were 6.7% (2/30) and 7.1% (2/28), respectively. The incidence of RBO was 35.7% (10/28). RBO was treated with an endoscopic transpapillary approach in eight patients and an endoscopic ultrasound-guided transmural approach in two patients. The median time to RBO was 162 days, and the median overall survival was 148 days.

conclusionsThis first prospective study investigating the SBSIS method demonstrated good technical feasibility with a low AE rate. Therefore, it can be considered a better option when contemplating trisectoral MS placement for high-grade MHBO.
