Multivariate Cox regression of prognostic parameters for survival in patients with colorectal cancer

Prognostic parameter	Multivariate analysis
	HR	95% CI	P value
Expression of ARHGAP15 (high vs. low)	3.07	1.57–6.01	0.001**
Clinical stage (I/II vs. III)	1.30	0.75–2.25	0.348
Tumor size ( < 4.0 cm vs. ≥ 4.0 cm)	3.07	1.49–6.31	0.002**
Metastasis (yes vs. no)	3.64	1.67–7.92	0.001**

HR: Hazard ratio; CI: Confidence interval. *P < 0.05, **P < 0.01
