Figure 4. Differentially enriched bacteria in saliva from the oral squamous cell carcinoma (OSCC) group when compared to the non-OSCC group. A: Linear discriminant analysis (LDA) of effect size showing bacteria observed in the OSCC and non-OSCC groups at the genus level. Correlation between CCL20 expression level and relative abundance of B: Fusobacterium (OSCC: 0.426, p=0.019; non-OSCC: −0.051, p=0.789); C: Porphyromonas (OSCC: −0.126, p=0.505; non-OSCC: 0.100, p=0.613); D: Treponema (OSCC: 0.101, p=0.594; non-OSCC: 0.073, p=0.714); and E: Streptococcus (OSCC: −0.310, p=0.095; non-OSCC: −0.275, p=0.157).
