Non-malignant lung tissue microbiota in relation to participants’ residential areas (a), particulate matter 10 micrometers in diameter (PM10) at enrollment (b) and tumor stage (c). The P values shown in a and c are based on Kruskal–Wallis tests but were also validated in an adjusted linear regression model (model with residential area, history of chronic bronchitis, and tumor stage). The P values in b are based on a linear regression model with PM10, history of chronic bronchitis, and tumor stage in the model. The asterisks in a indicate areas significantly different from the overall mean. Proteobacteria for residential areas and air pollution and Thermus for tumor stage are the only taxa that showed significant association according to both an adjusted linear regression model and a Kruskal–Wallis test with Bonferroni correction
