Table 5 Scanner-specific model performance after ComBat batch correction

CT scanner (manufacturer & model)	No. of cases (n)	Accuracy (%)	AUC (95%CI)
SOMATOM Definition Flash (Siemens, Munich, Germany)	45	64.4	0.78 (0.70-0.86)
Aquilion ONE (Canon Medical Systems, Otawara, Tochigi, Japan)	40	63.1	0.76 (0.68-0.84)
Aquilion 64 (Canon Medical Systems, Otawara, Tochigi, Japan)	35	62.9	0.77 (0.67-0.87)
Ingenuity Elite (Philips, Amsterdam, Netherlands)	32	64.0	0.79 (0.69-0.89)
Overall mean	152	63.6	0.78 (0.74-0.82)

Accuracy: Proportion of correct tricuspid regurgitation severity classifications. AUC: Area under the curve; CT: Computed tomography.
