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

Roux-en-Y gastric bypass (RYGB) is traditionally classified as a combined restrictive and malabsorptive operation. This notion of the operation influences its technical variations and revisions for patients who do not achieve significant weight loss after this surgery. There is an increasing body of literature suggesting a role for appetite suppression mediated by neuro-hormonal signals after RYGB. The purpose of this paper was to systematically review published English language scientific literature to determine the role of malabsorption towards weight loss achieved with RYGB. This review finds that there is little or no malabsorption of carbohydrates or protein after RYGB but there is some fat malabsorption. Overall, malabsorption makes a little (approximately 11.0% in the early period) overall contribution to weight loss after RYGB.
