Table 3. Multivariable Cox regression analysis for overall survival in luminal A breast cancer patients.

Variables	Luminal A breast cancer patients (n=226)
	HR	95% CI	P value
T stage (T3–T4 vs. T1–T2)	1.098	0.769–1.566	0.608
Histology grade (II–III vs. I)	1.924	1.140–3.250	0.014
NLR (≥2 vs. <2)	36.003	4.912–263.920	<0.0001

HR, hazard ratio; CI, confidence interval; NLR, neutrophil-to-lymphocyte ratio.
