Correlation networks of the top 50 most correlated genera among the IBS-D and TCM treatment group microbial communities. (a) The IBS-D-associated network. Pearson's correlation coefficients among the centered log-ratio-transformed bacteria were calculated, and correlations with coefficients ≥ 0.4 and P values < 0.05 were retained. In the network, each node represents a bacteria at genus level. The node size is proportional to the mean relative abundance of the bacteria. The orange lines between the nodes show positive correlation, and the green lines show negative correlation. (b) The medium dose of TCM treatment-associated network.
