The cohorts share a core gut microbiota composed of nine bacterial genera. (a) The proportion of each genus in the total sequences. (b) The abundance distribution of the nine genera and the collective core. Boxes represent the interquartile range (IQR) between the first and third quartiles. The lines and squares inside boxes represent the median and mean, respectively. Whiskers denote the lowest and highest values within 1.5 × IQR from the first and third quartiles, respectively. (c) The abundance of the collective core varies greatly across individuals in each cohort. Individuals in each cohort are arranged according to their abundance of the collective core. The cohorts are symbolized as in Figure 1.
