Table 5 Multivariate analysis¹.

Factors	Hazard ratio	95% CI	P
LOH (High vs Low)	3.18	1.68-5.98	<0.001
TNM	3.31	1.82-6.01	<0.001
CEA level
>5 ng/mL vs <5 ng/mL	2.3	1.21-4.37	0.011
Grade of differentiation	1.12	0.45-2.77	0.791
Lymphovascular invasion	1	0.49-2.01	0.981

¹The P value results from the hypothesis that the relative risk as determined by a multivariate binary logistic regression analysis equaled 1.0.
