Comparison of clean reads, human reads and microbial reads. A Proportion of clean reads to raw reads by Illumina or NEB. B Proportion of microbial reads to raw reads by Illumina or NEB. C Human reads in sample 1–9 of Microbial DNA, Total DNA, Total NA and Total RNA. D Microbial reads in sample 1–9 of Microbial DNA, Total DNA, Total NA and Total RNA. E Human reads in sample 10–13 of Total DNA, Total NA, Total RNA and WTA. F Microbial reads in sample 10–13 of Total DNA, Total NA, Total RNA and WTA
