Preoperative prediction of microvascular invasion in hepatocellular carcinoma using ultrasound features including elasticity

Table 5 Results of bivariate logistic regression of the features suggestive of positive microvascular invasion

Ultrasound features	β coefficient	Odd ratios	95% confidence interval	P value
Emax of the periphery of HCC	1.037 ± 0.467	2.820	1.128-7.049	0.027
Emax of HCC	0.114 ± 0.272	0.893	0.524-1.521	0.676
Maximal tumor diameter	0.021 ± 0.008	1.021	1.003-1.037	0.007
Surrounding liver tissue	0.329 ± 0.230	0.719	0.459-1.128	0.152
Color Doppler flow	0.324 ± 0.190	1.383	0.953-2.006	0.088

Emax: Maximal elasticity; HCC: Hepatocellular carcinoma.
