Relation between protein expression and survival (Univariate analysis)

Protein	P/N	HR	95% CI	P value
Membrane expression	P vs. N	3.521	2.232-5.556	<0.001a
Cytoplasm expression	P vs. N	1.475	0.955-2.278	0.080
Nuclear expression	P vs. N	0.526	0.175-1.580	0.252
Co-expression of membrane and cytoplasm	P vs. N	3.922	2.092-7.407	<0.001a

P/N indicates positive/negative; HR, hazard ratio; CI, confidence interval;
