Relative abundance of Bifidobacterium at the genus and species level. (A) Bifidobacterium relative abundance (%) grouped by age and diet. (B) Relative abundance (%) of all species identified within the Bifidobacterium genus and grouped by patient age. The lower and upper hinges of the box plots correspond to the first and third quartiles (the 25th and 75th percentiles), while internal hinge is the 50th percentile (median). Data beyond the end of the whiskers are "outlying" points and are plotted individually.
