Fig. 4. Bacterial taxa significantly associated with age development in the combined time points dataset.

a,b, Taxa identified through the MaAsLin2 R package analysis that are statistically associated with age (Supplementary Table 2) were plotted in a stacked line chart for the eleven 3-month age group intervals, separated by (a) positive association with age maturation and (b) negative association with age maturation. Only taxa with a minimum abundance of 0.2% were plotted. Absolute abundant bacterial 16S reads transformed using TSS and normalized using CSS + log₂ are shown on the y axis.
