To investigate the relationship between TINCR expression and the prognosis of cancer patients, Kaplan–Meier survival analysis and log-rank test were performed to assess the effects of TINCR expression and clinical outcomes on the survival of patients with breast cancer in the GEO database (two TINCR probes were used here, 244374-at/229385-at) (Supplementary Table S3) and other cancers in TCGA database. This evidence concerns the gene TINCR and breast cancer.
