A Prospective Multicenter Randomized Feasibility Trial of Double-guidewire Techniques for Difficult Biliary Cannulation Comparing a New Double-guidewire-supported Sphincterotome (MagicTome) to a Conventional Device.

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.
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
Objective To evaluate the effectiveness and safety of the double-guidewire technique (DGT) using a new double-guidewire-supported sphincterotome (MagicTome) for patients who required endoscopic retrograde cholangiopancreatography (ERCP) for biliary cannulation. Methods This prospective multicenter randomized feasibility trial involved patients with difficult biliary cannulation at any of the three study sites from June 2017 to October 2018. Patients were assigned to the DGT with MagicTome (MDGT) initially performed group and the conventional DGT (CDGT) initially performed group. The success rates of biliary cannulation by MDGT and CDGT and the ERCP-related complications were evaluated. Results Twenty-eight patients were included in this study. No significant difference was observed in the success rates of first attempts and crossover attempts between the groups (p=0.69 and p=1.00). Furthermore, no significant difference was observed in the success rate of biliary cannulation between MDGT and CDGT (62.5% and 75.0%, respectively; p=0.48). CDGT was successful in two of four patients with malignant biliary obstruction. MDGT was successful in all four patients with malignant biliary obstruction, including the two for whom CDGT was unsuccessful. Post-ERCP pancreatitis occurred in only one MDGT case. Conclusion MDGT is safe for biliary cannulation and can be used in cases where biliary cannulation by CDGT is difficult.
