Variable		HR (95% CI)	p Value
AFP (ng/mL)	≤150
	>150	35.23 (3.29–377.63)	<0.01
PET Positivity (Tumour/Background SUV Ratio)	≤1.15
	>1.15	28.03 (2.67–293.95)	<0.01
Treatment Group	Sirolimus
	Tacrolimus	15.00 (1.30–172.85)	0.03

HR, hazard ratio; CI, confidence interval; AFP, alpha-fetoprotein; PET, positron emission tomography; SUV, standardised uptake value.
