Per-patient sensitivity and specificity for the presence of active disease versus the consensus reference standard for patient groups combined

	Sensitivity					Specificity
	Patients with active disease*	MRE	Ultrasound	Difference	p value	Patients with inactive disease*	MRE	Ultrasound	Difference	p value
Active small bowel disease†	209	96% (92 to 99)	90% (82 to 95)	6% (2 to 11)	0·010	75	83% (68 to 92)	77% (60 to 88)	6% (−8 to 20)	0·376
Active colonic disease†	126	63% (48 to 76)	66% (51 to 79)	−3% (−18 to 13)	0·735	158	97% (91 to 99)	98% (94 to 99)	−1% (−4 to 1)	0·304
Active small bowel and colonic disease‡	251	77% (68 to 85)	66% (56 to 75)	11% (1 to 21)	0·024	33	28% (10 to 56)	28% (10 to 56)	0% (−26 to 26)	1·000

Data are n, % (95% CI), or p value. MRE=magnetic resonance enterography.

^*Patients by consensus reference standard.

^†Agreement with reference standard for disease active.

^‡Agreement with reference standard for active disease presence (patients with disease in the small bowel, colon, or both).
