The differential analysis of microbiota compositions between EIESC and controls at the phylum and genus level. A: the vertical bar chart presenting the oral microbiota compositions between EIESC and controls at the phylum level. The x-axis represents each sample and its group, and the y-axis represents the relative abundance. B-F: Boxplots showing the relative abundance of Firmicutes, Bacteroidetes, Proteobacteria, Firmicutes/Bacteroidetes (F/B) ratio, and Firmicutes/Proteobacteria (F/P) ratio in saliva samples. G: the vertical bar chart presenting the gastric microbiota compositions between EIESC and controls at the phylum level. H-L: Boxplots showing the relative abundance of Firmicutes, Bacteroidetes, Proteobacteria, F/B ratio, and F/P ratio in gastric biopsy samples. M-N: the vertical bar chart presenting the oral (M) and gastric (N) microbiota compositions between EIESC and controls at the phylum level. O: Volcano plot: the log2 fold-change indicates the mean relative abundance for each taxon. Each dot represents one genus. The blue dots represent no significant expression difference between the MHO and control groups, the red dots represent EIESC-enriched genus
