The CLU, ZBC or QIA reads represent the read numbers of identified microorganisms in DNA extracted using the CLU, ZBC, or QIA methods, respectively. The CLU, ZBC or QIA ratio represent the ratio of sequencing reads from microorganisms in the DNA extracted using the CLU, ZBC, QIA methods, respectively.
