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 Aims: Needle-knife access fistulotomy (NKF) involves using a needle-knife to cut into the intraduodenal segment of the bile duct, thereby avoiding the papilla. Previous studies suggest this procedure decreases the risk of post-ERCP pancreatitis and increases successful biliary cannulation compared with conventional methods. In this case series, we introduce an advanced endoscopic technique aimed at aiding endoscopists with successful NKF and broadening use of this procedure. Methods: Here we describe a technique in which we use the sphincterotome and needle-knife to palpate the intraduodenal biliary segment before needle-knife instrumentation. Careful dissection is then performed along this axis before achieving biliary cannulation with the sphincterotome and guidewire. Results: All videos shown led to successful biliary cannulation with next-day discharges from the hospital and clinical success with biliary decompression. Conclusions: Previous palpation for the bile duct may aid endoscopists with NKF. This may lead to wider adoption of NKF. Further prospective research is needed.
