Table 4 Cox regression analysis of the impact variables on overall survival

Variable	Univariate		Multivariate
	HR (95%CI)	P value	HR (95%CI)	P value
Mean tumor size (≥ 2.84 vs < 2.84)	0.550 (0.350-0.860)	0.008	0.650 (0.400-1.060)	0.085
Platelet count (≤ 125.42 vs > 125.42)	0.700 (0.500-0.980)	0.038	0.750 (0.520-1.080)	0.120
Surgical approach (LH vs RFA)	0.600 (0.420-0.860)	0.004	0.550 (0.380-0.790)	< 0.001

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