Figure 1. Increased KLRB1 levels were associated with diagnosis and better prognosis in BRCA using TCGA and K-M plotter databases. (A) KLRB1 expression in unpaired tissues; (B) KLRB1 expression in paired tissues; (C) The diagnostic effect of KLRB1 using ROC analysis; (D–F) The better prognosis related the KLRB1 overexpression in TCGA database by using K-M analysis; (G–I) Increased KLRB1 expression was associated with better OS, DMFS, and RFS of BRCA patients in K-M plotter database. Abbreviations: OS: overall survival; DMFS: distant metastasis-free survival; RFS: recurrence-free survival; ROC: Receiver operating characteristic; K-M: Kaplan-Meier.
