Fig. 3From: Old age and other factors associated with salivary microbiome variationSchematic of variables that are associated with variation of Bray–Curtis distances of the 3 groups. The x-axis represents the percentage of variance in the Bray–Curtis distance that are explained by the 6 variables. Blue bars are for factors that significantly explain variation in salivary taxa (p < 0.05). No value surpassed 1%Back to article page
