Heatmap of Spearman’s rank correlation coefficients of the relative abundances of different microbial communities and metabolites. (a) Negative ion mode. (b) Positive ion mode. Each square represents a Pearson correlation coefficient, while the gradation of color represents the size of each correlation coefficient. The red color represents a positive correlation, while the blue color represents a negative correlation. *P < 0.05, **P < 0.01.
