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

Bariatric surgery is effective for treating obesity and its comorbidities, but the optimal technique remains debated. This meta-analysis compared one-anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) in comorbidity remission and postoperative outcomes. We analyzed 12 trials, assessing T2DM, hypertension, and sleep apnea remission, as well as postoperative complications. Statistical analyses included risk differences (RD) and risk ratios (RR). OAGB was non-inferior to RYGB for T2DM remission (RD -1%; 95% CI -10% to 8%) but had higher risks of bile reflux (RR 7.62; 95% CI 1.97-29.46) and de novo GERD (RR 5.10; 95% CI 1.44-18.00). While OAGB is effective for T2DM remission, RYGB is superior in reducing bile reflux and GERD, highlighting the need for individualized surgical approaches.
