Hierarchical cluster of Bp and Rv patients according to OTU distribution at the genus level. The heat-map reports the hierarchical Ward-linkage clustering based on the Pearson’s correlation coefficient amongst OTUs at genus level. The color scale represents the scaled level of each variable: yellow, high level; blue, low level. The column bar is colored according to the subject category and clinical features’ groups. The left bar is colored according to the phylum level taxonomy.
