- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- healthy controls
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- breast cancer patients
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Breast cancer patients eligible were over 18 years of age, female, had tumors greater than or equal to 2 cm in size, were undergoing mastectomy. Patients receiving neo-adjuvant therapy prior to surgery or with active clinical breast infection were excluded from the study.

- 24
- Group 1 sample size Number of subjects in the case (exposed) group
- 39
Lab analysis
- Sequencing type
- 16S
- 16S variable region One or more hypervariable region(s) of the bacterial 16S gene

- No
Alpha Diversity
- Shannon Estimator of species richness and species evenness: more weight on species richness
- unchanged
