Learning models for colorectal cancer signature reconstruction and classification in patients with chronic inflammatory bowel disease

Table 1 Possible comparisons to be made during the unsupervised (i.e., we do not rely on the type of disease) global analysis of patients following the considered three different strategies

Strategy	Comparison
Strategy 1 (classic)	1 vs (2,3,4)
	2 vs (3,4)
	3 vs 4
Strategy 2 (1&1)	1 vs 2; 1 vs 3; 1 vs 4
	2 vs 1; 2 vs 3; 2 vs 4
	3 vs 1; 3 vs 2; 3 vs 4
	4 vs 1; 4 vs 2; 4 vs 3
Strategy 3 (pairwise)	1 vs (2,3,4)
	2 vs (1,3,4)
	3 vs (1,2,4)
	4 vs (1,2,3)
