Variables^	n	Univariable analysis			Multivariable analysis
		HR (95% CI)		P value	adjusted HR (95% CI)		P value
GEP/β-catenin
Low	61	1.0			1
High	16	1.9	(1.0-3.7)	0.041	2.2	(1.1-4.2)	0.019
Tumor stage
Early	51	1.0			1

^{^}GEP and β-catenin levels examined by real-time RT-PCR were modeled as categorical variables in the analyses.
