Table 3 Cox regression analysis of the impact variables on disease-free survival

Variable	Univariate		Multivariate
	HR (95%CI)	P value	HR (95%CI)	P value
Mean tumor size (≥ 2.84 vs < 2.84)	0.500 (0.310-0.810)	0.005	0.600 (0.370-0.970)	0.037
Platelet count (≤ 125.42 vs > 125.42)	0.667 (0.470-0.947)	0.022	0.700 (0.490-0.990)	0.045
Surgical approach (LH vs RFA)	0.550 (0.380-0.790)	0.001	0.500 (0.340-0.730)	< 0.001

HR: Hazard ratio; CI: Confidence interval; LH: Laparoscopic hepatectomy; RFA: Radiofrequency ablation.
