Fig. 7: Integrated multi-omics analyses reveal interconnected associations between core gut microbiota, host genes, and MCFAs.

Correlation network of core gut microbiota (hexagons) and MCFAs (circles) (A). Correlation network of core host genes (diamonds) and MCFAs (circles) (B). Positive and negative associations are represented by red and blue lines, respectively. Sankey plot integrating gut microbiota, MCFAs, and host genes, showing directional interactions within the STA-mediated regulatory axis (C). *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001.
