Risk Factors for Hepatocellular Carcinoma Recurrence and Survival after Liver Transplantation in Patients with HCV-Related Cirrhosis

Table 4

Results of multivariable Cox regressions for overall survival.

	HR	95% CI	value
Age	1.02	0.96-1.08	0.603
Transplantation waiting time	1.00	1.00-1.00	0.190
Alpha-fetoprotein ^a	1.01	1.00-1.02	0.006
>4 red blood cells units transfused during transplantation	1.15	1.05-1.25	0.001

^aThe results reported here for alpha-fetoprotein levels correspond to increases of 100 units of alpha-fetoprotein levels; i.e., the hazard ratio of 1.01 means that every increase of 100 ng/ml is associated with a 1% increase in the hazard of hepatocellular carcinoma recurrence.
