Box plot analysis of AR expression on CETCs in breast cancer patients with respect to lymph node and hormone receptor status. a We identified significant enhanced number of AR positive CETCs in patients without lymph node metastasis (N−) as compared to patients with lymph node involvement (N+), *P < 0.05. b In TNBC patients we observed elevated numbers of AR positive CETCs as compared to patients with HR positive primary tumors, *P < 0.05
