Survival analysis showed that despite no difference between expressions in normal and tumor tissues (Figure S3A and D) and no association with the infiltration of various immunocytes (Figure S3G and H), high expression of CD24 or PVR was significantly unfavorable for overall and disease‐free survival of patients with breast cancer (Figure S3B, C, E, and F). The gene discussed is CD24; the disease is breast carcinoma.
