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/Aims: To minimize the risk of post-procedure complications, air cholangiography has been proposed as an alternative to contrast cholangiography in patients with hilar biliary obstruction undergoing endoscopic retrograde cholangiography (ERCP). We compared the rate of post-ERCP complication between these two groups. Methods: We systematically reviewed all studies that compared the safety, success, and complication rate of air versus contrast cholangiography in malignant hilar obstruction patients. Results: A total of six studies consisting of 450 patients were included in the analysis. The overall rate of post-ERCP complication was less in the air cholangiography group (relative risk [RR]: 0.43, 95% CI: 0.30-0.61, Conclusion: In comparison to contrast cholangiography, air cholangiography had a better safety profile and a lower rate of post-ERCP complications.
