Stricturing (%)	6.3	20	16.2	57.5	<0.001	3.3	1.6–6.9
Fistulizing (%)	8.8	14	31.6	45.6	0.002	1.7	1.3–2.6
Inflammatory (%)	44	20.2	16.8	19	0.001	0.09	0.02–0.04

Small bowel surgery (%)	6.7	17	22	54.3	0.002	1.5	1.1–2.1

^*Numbers represent the percentage of antibody frequency in a specific disease phenotype. The microbial antigens include A4-Fla2, Fla-X, and ASCA.
