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

Information linking diet with the gut microbiome in bariatric surgery is limited. This pilot study examined correlations between macronutrient intake and gut microbiome indexes in adults undergoing bariatric surgery. Participants were 29 adults (93% female) undergoing bariatric surgery. Food records were used to estimate daily macronutrient intake. Shotgun sequencing was used in pre- and post-operative stool samples to identify changes in microbial composition. Diversity indices and differential abundance were calculated, and correlations between dietary intake and outcomes were assessed using linear regression and machine learning models. Phyla and genera were statistically correlated with macronutrient intakes, in particular, intake of soluble fiber, insoluble fiber, and dietary glycemic index. Changes in nutrient-related functional gene pathways were linked to change in HEI-2015 scores and in soluble and insoluble fiber intake following bariatric surgery. In this hypothesis-generating study, intakes of specific macronutrients were correlated with several microbial phyla, genera, and nutrient-related functional gene pathways.
