Association analysis of flora and metabolites with significant difference between the groups. A Spearman correlation coefficient matrix heat map of significant difference flora and metabolites; B Spearman correlation analysis hierarchical clustering heat map of significant difference flora and metabolites. The correlation coefficient R is expressed in color, where R > 0 indicates a positive correlation and is represented by red, R < 0 indicates a negative correlation and is expressed in blue. The darker the color, the stronger the correlation. P-value reflects the significant level of correlation and was defined by P < 0.05 as *, P < 0.01 as * *, P < 0.001 as * * *; C Correlation network diagram. The color of the line represents the positive and negative value of the correlation coefficient between the two (blue represents negative correlation and red represents positive correlation), and the thickness of the line is directly proportional to the absolute value of the correlation coefficient. The node size is positively correlated with its degree, that is, the greater the degree, the larger the node size.
