Relative abundance of bacterial families Veillonellaceae and Actinomycetaceae and their negative and positive correlation with age from adolescence to early adulthood. Veillonellaceae: P-value (Bonferroni corrected) 3.98 × 10−4; Pearson's r = −0.28700; Actinomycetaceae: P-value (Bonferroni corrected) 3.02 × 10−5, Pearson's r = 0.32188. Sample sizes: Age 12–14: n = 72; age 15–17: n = 88; age 18–21: n = 19; age 22–24: n = 55. The average relative abundance and ±SEM are plotted.
