Using the METABRIC dataset, we tested whether ITGA7 expression levels correlated with disease-free survival in a cohort of breast cancer cases (n = 1903; Fig. S6), or in the same cases separating them into those annotated as receiving chemotherapy (n = 396) and those not so annotated (n = 1507) (Fig. 2). This evidence concerns the gene ITGA7 and breast cancer.
