Alpha diversity of lung microbiota from lung cancer (LC) cases of The Cancer Genome Atlas (TCGA). (a) Inverse Simpson and Shannon indexes for LC cases grouped by histological subtype. (b) Inverse Simpson index of LC subtypes grouped according to different clinical variables available at TCGA database (ancestry, gender, age at diagnosis, smoking history, lung region and lung parenchyma). Welch’s t-test was used to access statistical significance of pairwise comparisons (*P-value < 0.05; **P-value < 0.01, ***P-value < 0.001). ADC: adenocarcinoma. SCC: Squamous cell carcinoma.
