Figure 4. The prognostic significance of UCK2 in breast cancer. Multivariable Cox regression analyses of UCK2 with overall survival (OS) (A) and disease-free survival (DFS) (B) in patients with adjustment for age, grade and estrogen receptor (ER) status. Cox regression analyses of UCK2 with OS in patients with ER− (C) and ER+ (D) breast cancer, respectively. Multivariable analyses of UCK2 with DFS in patients with ER− (E) and ER+ (F) breast cancer, respectively. Hazard ratios (HRs) and 95% confidence intervals (CIs) were adjusted for age and grade for (C–F).
