For the five clusters of Figure 2a, we give the number of samples per cluster (n) and their distributions over good/poor outcome, high/low lymphocytic infiltration (LI) score, and intrinsic subtypes as determined by the single sample predictor (SSP) classifier. Clusters were labeled by the main Gene Ontology of genes over-expressed in the group: CC⁺ (cell cycle), CC⁺/IR⁺ (cell cycle and immune response), ECM⁺ (extracellular matrix), SR⁺ (steroid hormone response), and IR⁺ (immune response). ER, estrogen receptor.
