- Case: lung tumor tissues, Control: tumor-adjacent normal tissues, NA: Not Available, * Five regions of the 16S rRNA gene were amplified and sequenced on Illumina HiSeq, MiSeq, or NextSeq. ** Dataset 2 (published) and Dataset 3 (unpublished) were separately available in SRA. With further assessment, we noticed both datasets had been taken from the same population. Therefore, we omitted the repeated samples and considered these two separate studies
