Table 7. Multivariate analysis of the colorectal liver metastases prognosis.

Survival time	P	HR (95% CI)
Differentiation (I/II vs. III/IV)	NS
Lymphatic metastasis (no vs. Yes)	0.021	1.921 (1.354–2.873)
Lymphatic or blood vessel invasion (no vs. Yes)	0.018	2.282 (1.099–4.452)
CUGBP1 low expression vs. CUGBP1 high expression	0.058	1.672 (1.089–2.385)

Multivariate analysis was performed using the Cox multivariate proportional hazard regression model with a stepwise method (backward, likelihood ratio).
