Purified diets containing high levels of soluble fiber and grain-based diets promote similar gastrointestinal morphometry yet distinct microbial communities.

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
Dietary fibers play a crucial role in shaping the gut microbiome and influencing gastrointestinal (GI) physiology. Grain-based diets (GBDs) are widely used in rodent studies, but their utility is limited due to batch-to-batch variability resulting from inconsistent ingredients. Purified diets (PDs) are composed of only known and refined ingredients and offer a solution to the constraints of GBDs. This study aimed to identify a combination of dietary fibers in a purified diet (PD) that promotes optimal murine gut morphometry and a diverse intestinal microbial community. Male C57BL/6J mice were fed either two grain-based diets (GBDs) or four PDs with varying fiber compositions for 28 days. Mice consuming PDs lacking soluble fiber had more gonadal fat ( IMPORTANCE: Dietary fibers are essential for maintaining gut health. Insoluble fibers aid in fecal bulking and water retention while soluble fiber is a fermentative substrate for intestinal microbial communities. Grain-based diets (GBDs) are commonly used in preclinical research but the variability in ingredients across batches impedes reproducibility. Purified diets (PDs), which are composed of highly refined ingredients, pose a potential solution but the most widely used low-fat control PDs contain no soluble fiber. This study intended to identify a PD with a combination of fibers that promotes murine gut health and microbial diversity. A PD with optimal fiber composition would aid in the standardization and reproducibility of studies investigating intestinal physiology and the gut microbiota.
