Table III.

Cox proportional hazards regression model was used in univariate analysis.

Characteristics	Hazard ratio (95% CI)	P-value
T-stage	1.040	0.883
(T1 vs. T2 vs. T3 vs. T4)	(0.612–1.768)
TNM-stage	2.458	0.011
(III vs. I and II)	(1.229–4.917)
Tumor size	1.106	0.663
(≥4 cm vs. <4 cm)	(0.702–1.744)
Apollon expression	0.855	0.005
(positive vs. negative)	(0.758–0.953)

TNM, tumor-node-metastasis; CI, confidence interval.
