Group 0 name Corresponds to the control (unexposed) group for case-control studies
HR- BC patients
Group 1 name Corresponds to the case (exposed) group for case-control studies
HR+ BC patients
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Slovakia breast cancer patients with hormone receptor status (HR+ vs HR-) was defined as positive for either oestrogen receptor or progesterone receptor vs negative for both, 1% of cells positive for hormone receptor was used as the cut-off to define hormone receptor positivity.
Group 0 sample size Number of subjects in the control (unexposed) group

Description: Differentially represented taxa in primary tumour tissues of Slovak patients between multiple markers statuses. For all comparisons, LEfSe was run with parameters: LDA > 3 (stricter than default LDA > 2 just for purpose of visualisation), Kruskal Wallis test p-value < 0.05, Wilcoxon test p-value < 0.05. (B) Comparison of the microbiome in primary tumours of patients positive on HR marker and negative on HR marker.

Abundance in Group 1: increased abundance in HR+ BC patients
