Graph shows bacterial community Shannon diversity index in relation to age. The linear regression indicates the increase of the Shannon diversity with age and is presented with a 95% confidence interval (A) (Pearson's r = 0.213, P = 0.003). The bar plot shows Pearson correlations of bacterial OTUs that significantly increase (blue) or decrease (red) in relative abundance with age (FDR < 0.05) (B).
