Group 0 name Corresponds to the control (unexposed) group for case-control studies: postoperation patients

Group 1 name Corresponds to the case (exposed) group for case-control studies: Carcinoma patients

Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group: The adenoma and carcinoma patients were diagnosed by colonoscopic examination and histopathological review of biopsies. Postoperative patients were classified as having NDA or CIT by follow-up surveillance colonoscopy and biopsies

Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any): 3 months

16S variable region One or more hypervariable region(s) of the bacterial 16S gene: V3-V4

Sequencing platform Manufacturer and experimental platform used for quantifying microbial abundance: Illumina

Data transformation Data transformation applied to microbial abundance measurements prior to differential abundance testing (if any).: relative abundances

Significance threshold p-value or FDR threshold used for differential abundance testing (if any): 0.1

MHT correction Have statistical tests be corrected for multiple hypothesis testing (MHT)?: Yes

Matched on Factors on which subjects have been matched on in a case-control study: age, body mass index, sex
