Table 2. Automated segmentation performance of EAT with the DL model.

Segmentation index	Internal set				External set
	Training	Validation	Test		Test
DSC	0.94±0.02	0.93±0.03	0.92±0.02		0.88±0.03
HD95 (mm)	0.66±0.13	0.93±0.31	0.88±0.28		0.99±0.52

Data are presented as the mean ± SD. EAT, epicardial adipose tissue; DL, deep learning; DSC, Dice score coefficient; HD95, Hausdorff distance 95%; SD, standard deviation.
