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
Health effects associated with microbial metabolites are influenced by dietary compounds and other environmental factors. Polyphenols derived from plant-based foods reach the large intestine mostly undigested, where they can interact with the gut microbiota. This explorative study investigated the metabolic responses of gut microbiota to the polyphenols rutin and genistein. Ex vivo anaerobic incubations with pooled fecal samples from volunteers with a BMI <25 (n = 7) and a BMI >40 (n = 7) were analyzed by ESI DI-FT-ICR-MS. Differences in metabolic diversity were observed between the two BMI groups, with the obese group showing a less diverse metabolic response. Metabolomic profiling identified 361 metabolites in 35 substance classes, with notable effects of the polyphenols on amino acid, carbohydrate, nucleotide, and lipid metabolism. Both BMI groups showed increased levels of dipeptides and amino acids and decreased levels of biogenic amines. Among the key findings, glutamine levels increased, which has been associated with obesity-related metabolic processes, while tryptophan levels were also elevated, a factor previously associated with obesity-related pathways. Glycine levels increased in both groups. Additionally, histamine, cadaverine, putrescine, and trimethylamine were reduced after exposure to the polyphenols. Changes in metabolites related to carbohydrate metabolism suggest an influence of rutin and genistein on sugar transport and cell wall synthesis. Furthermore, in the obese group, rutin exposure was associated with increased butyrate levels and decreased lactate levels. These findings contribute to a better understanding of how rutin and genistein interact with the gut microbiota metabolome, with potential implications for metabolic health and obesity-related research.
