Group 0 name Corresponds to the control (unexposed) group for case-control studies
WNH with TNBC normal tissue
Group 1 name Corresponds to the case (exposed) group for case-control studies
WNH with TNBC normal tissue
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Tumor tissue from white non-hispanic patients with triple negative breast cancer
Group 0 sample size Number of subjects in the control (unexposed) group

Group 1 sample size Number of subjects in the case (exposed) group
6
Antibiotics exclusion Number of days without antibiotics usage (if applicable) and other antibiotics-related criteria used to exclude participants (if any)
Biorepository information revealed that no patients were treated with antibiotics prior to tissue sample collection, however duration window of non-exposure was unidentified.
