Table of P-values based on distance-based ANOVA with 10,000 label permutations comparing average UniFrac distances within (A) and between vs. within (B) bacterial microbiota from smoking and nonsmoking groups by airway site sampled. Significance threshold: P-value<0.05.
In all cases, bacterial communities from smokers had greater average within-group distances.
In all cases, bacterial communities from smokers had greater average between vs. within-group distances.
