Multiomics analysis reveals that microbiota regulate fat and muscle synthesis in chickens.
Article in Poultry science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Intestinal microbiota regulates the host metabolism, including fat metabolism and muscle development in mammals; however, studies on the interactions between the gut microbiome and in chickens with respect to fat metabolism and muscle development are still rare. We established a germ-free (GF) chicken model to determine the transcriptomes and metabolomes of GF and specific-pathogen-free (SPF) chickens. Transcriptome analysis showed 1,282 differentially expressed genes (DEGs) in GF and SPF chickens. The expression levels of some genes related to muscle formation were very high in SPF chickens but low in GF chickens, suggesting that GF chickens had poorer muscle development ability. In contrast, the expression levels of some fat synthesis-related genes were very low in SPF chickens but high in GF chickens, suggesting that GF chickens had a more potent fat-synthesizing ability. Metabolome analysis revealed 62 differentially expressed metabolites (DEMs) in GF and SPF chickens, of which 35 were upregulated and 27 were downregulated. Furthermore, the Pearson correlation coefficient (PCC) was calculated, and an interaction network was constructed to visualize the crosstalk between the genes, metabolites, and gut microbiota in GF and SPF chickens. The top 10 gut microbiota were positively correlated with lipid metabolism including13(S)-HpODE and 9(S)-HpOTrE, and genes related to muscle development, while were negatively correlated with genes related to fat synthesis. In conclusion, this study indicated that chicken intestinal microbiota regulate host metabolism, inhibit fat synthesis, and may promote muscle development.
