Gene composition and functional annotation of saliva and dental plaque in cancer patients. (A) PCoA analysis (80% confidence interval). (B) Correlation test between samples at the genetic composition level. The distance between points in a scatter plot represents the correlation between two genes. (C) Analysis of inter group differences in functional pathways with the top 50 abundances at level 2 of the KEGG database (T-test, P < 0.05). The color of the bars represents different groups, and the length of the bars represents abundance information. (D) Volcano plot showing the relative abundance differences of genes, where red points indicate significantly higher relative abundance of the gene in the saliva group (P < 0.05, log2FoldChange > 2). Blue points indicate significantly lower relative abundance in the saliva group (P < 0.05, log2FoldChange < -2), and grey points indicate no significant difference
