Factors	OS relative risk	95% CI	P value
Gender (male vs. female)	1.224	0.785-2.673	0.387
Age (> 60 vs. <=60)	1.432	0.824-3.321	0.149
Tumor size (>5cm vs. <=5cm)	1.893	0.573-4.328	0.532
Tumor stage (III+IV vs. I+II)	3.345	1.435-6.536	0.002
Tumor location (left vs. right)	0.892	0.346-1.573	0.674
Differentiation (low vs. high)	2.573	1.323-5.423	0.015
Metastasis	3.675	2.035-5.269	0.000
MiR133b expression (low vs. high)	2.743	1.047-5.013	0.000
HOXA9 expression (high vs. low)	1.652	1.015-4.360	0.036

Univariate analysis was performed by the Cox proportional hazards regression model. CI: confidential interval; OS:overall survival.
