Table 2. Univariate and Multivariate Analyses of Factors in Overall Survival and Recurrence-Free Survival After Treatment.

Factors	Overall survival			Recurrence-free survival
	P value for univariate	Multivariate		P value for univariate	Multivariate
		HR (95% CI)	P value		HR (95% CI)	P value
Tumor size (≤3/>3), cm	<.001	1.64 (1.14-2.35)	.007	.01	1.24 (0.89-1.74)	.20
No. of tumors (≤1/>1)	.02	1.27 (0.90-1.79)	.18	.03	0.98 (0.72-1.35)	.91
AFP (≤400/>400), ng/mL	.01	0.95 (0.82-1.10)	.51	.02	0.97 (0.85-1.11)	.63
Treatment allocation (RFA vs TACE-RFA)	<.001	1.78 (1.26-2.51)	.001	.001	1.497 (1.105-2.029)	.009

Abbreviations: AFP, α-fetoprotein; HR, hazard ratio; RFA, radiofrequency ablation; TACE, transcatheter arterial chemoembolization.

SI conversion factor: To convert AFP to μg/L, multiply by 1.0.
