- Group 0 name Corresponds to the control (unexposed) group for case-control studies
- Ki67 < 20% BC patients
- Group 1 name Corresponds to the case (exposed) group for case-control studies
- Ki67 > 20% BC patients
- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- Slovakia breast cancer patients were labeled Ki67 > 20% or Ki67 < 20%. Ki-67 labelling index was reported as a percentage of cells with Ki-67 positive nuclear immunostaining.

Signature 1
Source: Figure 4 (E)
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. (E) Comparison of the microbiome in primary tumours of Ki67 > 20% and Ki67 < 20%.
Abundance in Group 1: increased abundance in Ki67 > 20% BC patients
