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

backgroundPartially covered self-expandable metallic stents (PCSEMSs) used for endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) provide favorable patency and low migration risk; however, reintervention (RI) remains challenging. OBJECTIVES AND

methodsWe retrospectively evaluated the outcomes of RI after EUS-HGS with PCSEMS placement in 108 patients with malignant biliary obstruction treated between January 2016 and December 2024. Causes of recurrent biliary obstruction (RBO), RI techniques, and post-RI outcomes were analyzed.

resultsThe median age of patients was 77 years, with pancreatic cancer being the most common (n = 62). RBO occurred in 25 (23%) patients, including those with sludge/food impaction (n = 15) and hyperplasia (n = 10). The median time to RBO (TRBO) was 196 days. RI involved PCSEMS removal and replacement (n = 11), or treatment without removal (n = 12). Post-RI RBO developed in six patients (24%), and the median post-RI TRBO was 185 days. The removal group showed a significantly longer TRBO than the nonremoval group (185 vs. 77 days; p = 0.048). Hyperplasia was an independent predictor of failed stent removal (OR, 18.7; 95% CI, 1.45-240; p = 0.02).

conclusionsStent removal during RI is associated with longer post-RI TRBO; however, removal can be challenging, particularly in cases with hyperplasia. Careful selection of a PCSEMS for EUS-HGS is required based on the patient's life expectancy.
