Fistulotomy-First Approach is Safe and Effective in Endoscopic Retrograde Cholangiography: Results of a Prospective Case Series.
Article in Journal of the Canadian Association of Gastroenterology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
BACKGROUND AND
aimsThe aim of this study was to assess the safety and efficacy of using needle-knife fistulotomy (NKF) as a primary cannulation technique in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) with a native papilla. PATIENTS AND
methodsThis prospective feasibility study enrolled 50 patients between December 2018 and June 2019. The procedure was performed by two expert endoscopists (R.B. and L.H.). The primary outcome was the incidence of post-ERCP pancreatitis. Other variables assessed included the success rate of cannulation of the common bile duct (CBD), time to successful cannulation, and incidence of adverse events.
resultsBetween December 2018 and June 2019, 50 patients enrolled in the study. The mean age was 63.4 years (standard deviation 18.1), and there were 26 females. Indications included biliary obstruction secondary to malignancy (
conclusionsIn this pilot study, NKF was used as the primary biliary access technique and it was demonstrated that it appears to be at least as safe as the traditional access technique with a sphinctertome. However, its role as a primary cannulation technique requires further investigation with multicenter, randomized control studies.
