Group 0 name Corresponds to the control (unexposed) group for case-control studies: carier of pathogens controls

Group 1 name Corresponds to the case (exposed) group for case-control studies: Type-2 DM cariers of pathogens

Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group: The non-carrier meant that the individual did not have sequence read for the specific pathogen.

Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any): 2 months

Lab analysis

Sequencing type: 16S

16S variable region One or more hypervariable region(s) of the bacterial 16S gene: V5-V6

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

Statistical Analysis

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

Statistical test: T-Test

Significance threshold p-value or FDR threshold used for differential abundance testing (if any): 0.05

MHT correction Have statistical tests be corrected for multiple hypothesis testing (MHT)?: No

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

Confounders controlled for Confounding factors that have been accounted for by stratification or model adjustment: alcohol drinking, blood pressure, body mass index, smoking behavior, total cholesterol measurement, triglycerides
