Fig. 4

Level 3 KEGG functional pathways of WGCNA high correlated Modules (Blue [A]; Brown [B]) and hub ASVs in module blue (MEblue) (C) and module brown (MEbrown) (D) characterized by Level 2 pathways. This figure displays the top 30 abundant KEGG pathways. To enhance clarity, the bar length means the relative abundance of KEGG pathways at level 3. The different colors of bar represent the different level 2 pathways, which are described in the grey box on the right side of the figure
