Distance based redundancy analysis (db-RDA) of infant gut microbiome. Subjects belonging to the intervention groups, Control C-section (C), Prebiotics C-section (P), Synbiotic C-section (S) and the Reference group (R) are indicated by the red, green, purple and blue circles respectively. The db-RDA axes describe the percentage of the fitted and total variation explained by each axis while being constrained on groups. Black arrow vectors indicate the weight and direction of 10 most important bacterial genera. The labels for the groups, Control C-section (C), Prebiotics C-section (P), Synbiotic C-section (S) and the Reference group (R) are located at the geometrical center of each intervention group. * represents P < 0.05 (PERMANOVA test)
