Here, 1981, 508, 286 and 251 samples of gene expression profiles were used from the METABRIC, GSE25066, GSE22034, and GSE3494 datasets, respectively. The METABRIC data set is used for training, and three GSE (GSE25066, GSE2034, and GSE3494) datasets are used for validation. METABRIC, GSE25066, and GSE2109 datasets were used to find differentially expressed genes (DEGs) between TNBC vs. non-TNBC. The numbers located in table represent the number of samples according to breast cancer characteristics
