The Prognostic Value of the Expression of SMC4 mRNA in Breast Cancer

Table 2

Multivariate Cox regression analysis for risk factors associated with OS in female non-TNBC patients from the TCGA cohort from 2001 to 2013 ().

Characteristics	HR	95% CI
Age >65 vs. ≤65	7.372	2.902-18.727	<0.001
Stages III-IV vs. stages I-II	4.370	1.745-10.949	0.002
PR negative vs. PR positive	4.296	1.628-11.336	0.003
High SMC4 vs. low SMC4	3.293	1.257-8.625	0.015

TNBC = triple negative breast cancer; HR = hazard ratio; CI = confidence intervals; PR = progesterone receptor; SMC4 = structural maintenance of chromosomes protein 4. Wald forward with SMC4 expression and all the characteristics.
