Class prediction accuracy of the two models SEG and noSEG on the external test set polyp segmentations for each histopathologic category

Histopathologic category	Model accuracy		Ground truth classification
Histopathologic category	SEG	noSEG	Ground truth classification
Regular mucosa	3/9 (33%)	7/9 (78%)	Benign
Hyperplastic polyp	21/30 (70%)	15/30 (50%)
Lipomatous polyp	0/0	0/0
Tubular adenoma	36/49 (73%)	37/49 (76%)	Premalignant
Tubulovillous adenoma	23/26 (88%)	23/26 (88%)
Villous adenoma	0/0	0/0
Serrated adenoma	0/0	0/0
Adenocarcinoma	4/4 (100%)	3/4 (75%)

The four adenocarcinoma segmentations were included in the premalignant group for study purposes only
