Fig. 2: Beta diversities and their contributors between mAge deviation groups.

Robust principal component analysis (n = 311 biologically independent samples) (A), phylogenetic robust principal component analysis (n = 311) (B), and Bray–Curtis principal coordinate analysis (n = 303 after rarefaction) (C) with samples coloured according to their corresponding mAge deviation group. The percentage of variance explained in (A) and (B) is based on the proportion of the three computed eigenvalues, whereas in (C), it is compared to the total variance across all eigenvalues. In (D), contributions of ASVs to group differences based on Bray–Curtis distances are displayed (n = 303), calculated using SIMPER with 999 permutations. ASVs above the dashed line show significant contributions at unadjusted p ≤ 0.05. The six most abundant ASVs across the entire dataset are annotated at the species level. Mean abundance refers to the average abundance of a given ASV across mAge deviation groups. PC principal component, PCo principal coordinate.
