NTF4 and breast cancer: To assess the association between NTF4 expression and breast cancer patient survival, Kaplan-Meier curves with log-rank test were used to determine overall survival (OS), distant-metastasis-free survival (DMFS), and progression-free survival (PFS) of breast cancer patients derived in different stage from TCGA (The Cancer Genome Atlas, https://portal.gdc.cancer.gov/).
