Moderate increase in dietary fat induces alterations of microbiota and metabolome along the digestive tract prior to systemic metabolic changes: insights from a pig model.

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.
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
The small intestine is a key site for nutrient sensing and host-microbiota interactions, yet how it functionally adapts to dietary changes remains poorly understood. Using a translational porcine model, we investigated the impact of moderate dietary fat increase on the gut microbiota and metabolome across five locations in the digestive tract. Pigs were fed either a low-fat (3%) or a medium-fat (12%) diet for 12 weeks without developing obesity. Multiomics profiling revealed significant dietary effects on bile and duodenojejunal metabolomic profiles, particularly lipid and stachydrine, with notable sex-specific responses. These metabolite shifts were accompanied by segment- and sex-specific changes in microbial communities, including the depletion of metabolically beneficial taxa (e.g.,
