Table 2 Performance of INHEARIT fine-tuned with item 2 (SA, moderate augmentation) with various dataset combinations.

Experiment	Number of Original Patches	Dataset	Augmentation	IoU (Avg ± SD)	IoU₍₂₎^a
4	110	SA → FA	Low	0.686 ± 0.026	+
			Moderate	0.724 ± 0.030	+
			High	0.749 ± 0.013	+
5	372	SA → FASA	Low	0.702 ± 0.032	+
			Moderate	0.760 ± 0.014	+
			High	0.761 ± 0.036	+
6	60	SA → FA’	Low	0.610 ± 0.040	−
			Moderate	0.743 ± 0.031	+
			High	0.716 ± 0.027	+
7	322	SA → FA’SA	Low	0.642 ± 0.025	+
			Moderate	0.678 ± 0.018	−
			High	0.674 ± 0.016	−

IoU = intersection-over-union; Avg = average; SD = standard deviation; SA = selectively annotated dataset; FA = fully annotated dataset; FA’ = main organs only in FA, FASA = both SA and FA, FA’SA = main organs only in FASA; IoU = intersection-over-union.
^aLoss (−) or gain (+) in IoU compared with Experiment 2 in Table 1 at the same augmentation scale.
Numbers in bold indicate the highest performance for each item.
