Cox proportional hazards analyses of RFS in 307 patients with HCC

Variables	SE	Wald	Exp(B)	95% CI	P-value
Maximum tumor size (≥5 vs <5 cm)	0.198	12.022	1.985	1.347–2.926	0.001
AFP (≥400 vs <400 µg/L)	0.167	4.927	1.448	1.044–2.009	0.026
Microscopic vascular invasion (yes vs no)	0.225	9.622	2.009	1.293–3.121	0.002
STR (yes vs no)	0.203	0.077	0.945	0.635–1.407	0.782

Abbreviations: AFP, α-fetoprotein; CI, confidence interval; HCC, hepatocellular carcinoma; RFS, recurrence-free survival; SE, standard error; STR, spontaneous tumor rupture.
