Table 6. Cox regression analysis^# for overall survival and disease-free survival in HCC-A patients.

Survival analysis	Strata variable	Prognostic factor	B	SE	HR(95.0% CI)	p
Overall survival	None	CD5L	−0.205	0.071	0.814(0.709–0.936)	0.004**
	Pathological stage	None
Disease-free survival	None	CSMD1	0.432	0.126	1.540(1.204–1.970)	0.001**
	Pathological grade	CSMD1	0.315	0.123	1.370(1.076–1.744)	0.021*

Notes:

SKGs, special key genes; B, regression coefficient; SE, standard error; HR, hazard ratio; CI, confidence interval.

^#Forward Stepwise (Likelihood Ratio) method was used for Cox regression analysis with 13 variables including the 10 genes in SKGs, gender, age at diagnosis, and family history of cancer as covariates.

*p < 0.05; **p < 0.01; p < 0.05 was considered to be statistically significant.
