Logistic regression for gross type.

Clinicopathological feature	Unit	OR	(95% CI)	P-value
Age	10	1.175	(0.654–2.111)	0.5905
Sex	Female/Male	0.74	(0.091–6.035)	0.7786
Histological grade	Mode/Poor	0.654	(0.065–6.585)	0.7184
RGS5	1	3.628	(1.291–10.196)	0.0145
AFP	480	0.928	(0.788–1.093)	0.371
DCP	500	1.036	(0.968–1.108)	0.3079

RGS5 expression, serum AFP levels and serum DCP levels were treated as continuous variables and units for the OR were determined referring difference between upper and lower 25 percent percentiles. OR, odds ratio; CI, confidence interval; RGS5, regulator of G-protein signaling 5; AFP, α-fetoprotein; DCP, des-γ-carboxyprothrombin; Mode, moderately-differentiated hepatocellular carcinoma; Poor, poorly-differentiated hepatocellular carcinoma.
