– Bacteria relative abundance composition and comparison of oropharyngeal and fecal samples at the phylum level: The composition of bacterial relative abundance are shown in bar plots: panel a) oropharyngeal (OP) samples and c) fecal samples. The major phyla (relative abundance >1.0%) comparisons between AC and CC children are shown on box plots in panel b) OP samples and d) fecal samples. The top and bottom lines of box plots show the interquartile range, and lines inside the boxes represent medians, and black dots represent outliers.
