Clinical and radiomic characteristics of transarterial chemoembolization combined with immunotherapy in hepatocellular carcinoma

Table 6 Correlation analysis between radiomics features and clinical features

Clinical features	Radiomic features	Correlation coefficient (r)	P value
Tumor volume	GLCM contrast	-0.43	< 0.01
Tumor volume	DCE-MRI arterial phase entropy	0.48	< 0.01
Tumor location	GLRLM SRHGE	0.40	< 0.05
Tumor location	GLDM gray-level non-uniformity	0.45	< 0.01
Tumor number	Gray-level variance of texture features	0.52	< 0.01
Tumor number	GLRLM LRLGE	-0.46	< 0.01

GLCM: Gray-level co-occurrence matrix; DCE-MRI: Dynamic contrast-enhanced magnetic resonance imaging; SRHGE: Short-run high-gray-level emphasis; LRLGE: Long-run low-gray-level emphasis.
