Figure 7. Time-series analyses of HNSCC patients (n=11) for whom we had repeated saliva samples, according to both sampling sites, HPV status and TNM staging.

Bacterial communities were noticeably different between T1-2N2AM0 and T3N2BM0 TNM stage. Lactobacillus spp. were significantly more abundant in patients with T3-2N2BM0 staging (p<0.01, G-test). Legend indicates genus that show a relative abundance higher than 1%.
