Relative abundance of bacterial phyla in the microbiota of lung cancer subtypes and normal lung samples. Differential abundance across phyla were identified based on the univariate analysis (Mann-Whitney test). Actinobacteria (LUAD vs. normal p-value < 3.2e-2, LUSC vs. normal p-value < 13.2e-4), Bacteriodetes (LUAD vs. normal p-value < 3.8e-5, LUSC vs. normal p-value < 3.6e-3) were significantly different when both subtypes of NSCLC were compared with normal. Firmicutes (p-value < 1.3e-5) and Proteobacteria (p-value < 6.4e-4) were significantly different in abundance then the NSCLC subtypes.
