Univariate and multivariate analyses of prognostic factors associated with tumor progression and overall survival

Clinicopathological characteristics	TTP				OS
	Univariate	Multivariate			Univariate	Multivariate
	P	P value	HR	95% CI	P	P value	HR 95% CI	95% CI
Gender (female vs. male)	0.37	NS			0.30	NS
Age, years (<50 vs. ≥50)	0.92	NS			0.18	NS
HBV (no vs. yes)	0.17	NS			0.52	NS
AFP ug/L (≤20 vs. >20)	0.11	NS			0.44	NS
Child-Pugh grade (A vs. B)	0.23	NS			0.04	NS
Tumor number (single vs. multiple)	0.04	NS			0.71	NS
RFA treatment	<0.001	<0.001	0.39	0.27-0.56	0.01	0.01	0.51	0.31-0.86

AFP: alpha-fetoprotein; HBV: hepatitis B virus; CI: confidential interval; HR: hazard ratio.

NS: not significant; OS: overall survival; TTP: time to progression; RFA: radiofrenquency ablation.
