BACH1 and neoplasm: When we further analyzed their correlation in each tumor subtype, we similarly observed a positive but insignificant trend between BACH1 and MCT1 in the basal-like (0.226, p = 0.222; N = 31), luminal A (0.237, p = 0.048; N = 70), and luminal B (0.353, p = 492; N = 6) subtypes (Figure 6B).
