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 study aims: Endoscopic ultrasound-guided pancreaticogastrostomy (EUS-PGS) is performed for patients who have failed ERCP. Tract dilation is one of the challenging procedural steps during EUS-PGS. Recently, a bougie dilator, the drill dilator, has become available. With this device, tract dilation can be easily performed without pushback of the echoendoscope, allowing stable scope positioning to be achieved during tract dilation. However, comparative studies between ultra-tapered mechanical and drill dilators have not been reported. The aim of this study was to compare the technical outcomes of these dilation devices. Patients and methods: Symptomatic patients with main pancreatic duct (MPD) strictures from January 2021 to November 2023 were included in this retrospective study. The technical success rate of tract dilation was first evaluated. Overall technical success rate, procedure time, and adverse events were evaluated as secondary outcomes. Results: The technical success rate of initial device insertion into the MPD was higher with the Tornus ES (100%, 12/12) compared with the ES dilator (60%, 9/15) ( Conclusions: In conclusion, Tornus ES might be considered as the initial dilation device during EUS-PGS.
