Correlation analysis between dominant gut microbiota and SCFA. A The correlation between the dominant changed gut microbiota at the genus level and SCFAs is displayed in the heatmap. The red‒white-blue grid corresponds to the value of (− 1)-to-1. Red color, positive correlation; blue color, negative correlation. Correlations were calculated in MaAsLin analysis: B Ileibacterium (coefficient = 0.001812, p = 0.007009), C Dubosiella (coefficient = 0.008104, p = 0.000146), D Lachnospiraceae_NK4A136_group (coefficient = − 0.003266, p = 0.047813) and E Lactobacillus (coefficient = − 0.001291, p = 0.025955). The color and shape of points represent individuals in each group. *p < 0.05, **p < 0.01, ***p < 0.001. n = 5. MaAslin, Multivariate Association with Linear Models
