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

This study aimed to investigate the efficacy of one-anastomosis gastric bypass (OAGB) on gastroesophageal reflux disease (GERD) compared with Roux-en-Y gastric bypass (RYGB) in patients with obesity. Three databases (Medline, Cochrane Central, and Scopus) were searched for relevant articles published until August 12, 2024. A total of nine randomized controlled trials, including 643 patients, were selected. OAGB was statistically significantly associated with a higher risk of GERD than RYGB (OR = 3.14, 95% CI 1.23-8.03, p < 0.05). The odds for de novo GERD after OAGB are almost six times higher than after RYGB (OR = 5.65, 95% CI 1.53-20.82, p < 0.05). RYGB has a lower incidence of de novo GERD cases and is more effective than OAGB in reducing GERD.
