KLF11 and breast cancer: Furthermore, regarding DMFS, univariate cox regression revealed that KLF11 (HR = 2 0.132, 95% CI = 1.125–4.043, p = 0.020), molecular subtype (HR = 1.772, 95% CI = 1.054–2.981, p = 0.031), grading (HR = 2.689, 95% CI = 1.281–5.644, p = 0.009), tumor size (HR = 3.044, 95% CI = 1.818–5.099, p < 0.001) and lymph node status (HR = 2.328, 95% CI = 1.355–3.998, p = 0.002) were significantly associated with DMFS in BC (Table 3).
