Elevated CXCL1 expression in breast cancer stroma predicts poor prognosis and is inversely associated with expression of TGF-β signaling proteins

Table 3 Relationship between known prognostic factors and CXCL1 RNA expression in breast cancer stroma

Prognostic factor	r	95% CI	p-value
Age	-0.13	-0.41 to 0.17	0.38
Tumor size	-0.004	-0.31 to 0.30	0.97

Associations were determined using Spearman Correlation analysis of data obtained from the Finak microarray database. Significance determined by p<0.05.
r= correlation coefficient. N=53.
