Fig. 2From: High incidence of triple negative breast cancers following pregnancy and an associated gene expression signatureClustering of tumor samples based on the gene set of a 14 genes including ESR1, PGR, and ERBB2, and b 11 genes excluding ESR1, PGR, and ERBB2. Samples labeled with 1 are TNBCs, samples labeled with 0 are non-TNBCs.
