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

backgroundNeedle-knife precut papillotomy (NKP) is typically performed freehand. However, it remains unclear whether pancreatic stent (PS) placement can improve the outcomes of NKP.

aimTo explore whether PS placement improves the success rate of NKP in patients with difficult biliary cannulation.

methodsThis single-center retrospective study included 190 patients who underwent NKP between January 2017 and December 2021 after failed conventional biliary cannulation. In cases with incidental pancreatic duct cannulation during conventional biliary cannulation, the decision for pre-NKP PS placement was made at the endoscopist's discretion. The primary outcome was the difference in the NKP success rate between patients with and without PS placement; the secondary outcome was the adverse event rate.

resultsAmong the 190 participants, 82 received pre-NKP PS (PS-NKP group) whereas 108 did not [freehand or freehand NKP (FH-NKP) group]. Post-NKP selective biliary cannulation was successful in 167 (87.9%) patients, and the PS-NKP had a significantly higher success rate than the FH-NKP group (93.9%

conclusionPS significantly improved the success rate of NKP in patients with difficult biliary cannulation.
