Descriptive statistics for the microbiome discovery cohort

(A) age distribution (B) richness and Pielou’s evenness index of active microbial richness by decade (C) richness and Pielou’s evenness index for active functions (D and E) mean CLR transformed expression levels of species/KOs by age for most variable species/KOs grouped by genus or Viome Functional Categories (see main text). In the boxplots shown in Figures 1B and 1C, the box denotes the quartiles and the whiskers extend 1.5 IQRs (Inter Quartile Range) above and below. See Table 1 for details regarding the discovery cohort.
