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

backgroundPost-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is a critical and poorly managed complication of ERCP. Endoscopists need to understand the risk factors for PEP. However, the majority of studies investigating ERCP-related risk factors have included well-trained endoscopists, with the issue of endoscopist experience on PEP incidence not having been systematically evaluated.

aimTo explore the risk factors for PEP in beginner endoscopists without supervision.

methodsWe performed a retrospective analysis of 293 patients, with naïve papilla and no history of pancreatitis, treated using bile duct cannulation. Patients were classified according to the endoscopist's experience (beginner

resultsAfter propensity matching, there were no differences between patients treated by the expert and beginner endoscopist with regard to age, sex, mean bile duct dilatation, and ratio of benign disease. The distal CBD angle was classified as acute (> 30º) or obtuse (≤ 30º), based on the mean angle of 29.9º for the group. An acute distal CBD angle was a significant risk factor for PEP for beginner (

conclusionFor beginner endoscopists first performing unsupervised ERCP, cases with an obtuse distal CBD angle may be more appropriate to lower the risk of PEP.
