table 2. Univariate and Multivariate Analyses of Prognostic Factors for HCC Occurrence

Variable	Number of Patients	Univariate Analysis		Multivariate Analysis
Variable	Number of Patients	P^*	Relative Risk (95% CI)	P	Relative Risk (95% CI)

Transfusion No	44
Yes	59	.03	6.7 (0.9-52.5)	NS
Alk. Ph. 87 IU/L	83
>87 IU/L	20	.01	5.9 (1.7-20.2)	NS
Prothrombin time 63%	86
<63%	17	.0004	6.6 (2-22)	NS
IFN Yes	59
No	44	.0006	7.8 (2-29.7)	.02	6.0 (1.3-28.7)

Abbreviations: NS, not significant; CI, confidence interval; Alk. Ph., alkaline phosphatase. ^* P values were obtained by using the log-rank test. P values were obtained by using Cox regression analysis. Relative risks were calculated by comparing classes with Cox regression analysis.
