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

backgroundRoux-en-Y gastric bypass (RYGB) has long been established as one of the most efficient therapeutic options for patients with obesity and associated medical conditions. However, the impact of concurrent vagal transection during pouch creation on postoperative outcomes remains underreported.

methodsThis retrospective cohort study examined patients who underwent RYGB between January 2011 and December 2023, with 1 to 5 years of follow-up. Patients were stratified into two groups: vagal sparing RYGB (VS) and non-vagal sparing RYGB (NVS). Data collected included postoperative complications, intraoperative characteristics, weight trajectories, resolution of obesity-related medical conditions, and mortality. Statistical analysis methods included paired t-tests, multivariate regression, and Cox regression models.

resultsOut of 1521 patients, 374 (24.6%) underwent VS-RYGB and 1147 (75.4%) had NVS-RYGB. Patients were predominantly female (80.8%), with a mean age of 47.6 ± 12.1 years and body mass index (BMI) of 46.0 ± 7.7 kg/m

conclusionNVS-RYGB was associated with higher operative time. Additionally, vagal transection was significantly associated with marginal ulcer occurrence. Our findings support the potential advantage of vagal-sparing RYGB.
