By analyzing the correlation between the microbiota and inflammatory indexes in patients with oral cancer (Figure 7C), we found that P.intermedia was positively correlated with procalcitonin (PCT), C-reactive protein (CPR), IL-6, and The neutrophil ratio (Nent), while S.mitis was negatively correlated with procalcitonin (PCT), C-reactive protein (CPR), IL-6, The neutrophil ratio (Nent), and white blood cells (WBCs). This evidence concerns the gene CALCA and lip and oral cavity carcinoma.
