Demographic characteristics and pulmonary function test results of the study groups

Disease	(n)	Age (range)	Sex (F/M)	FEV (%)	DLCO (%)	TLC (%)
Crohns disease (CRD)	(18)	22–80	9/9	97·6 ± 18·7	94 ± 15·8	92 ± 23·8
Sarcoidosis (SA)	(13)	46–68	6/7	80·5 ± 24·2*	79·4 ± 12·9†	92·8 ± 27·8
Controls (CO)	(9)	20–60	3/6	96·2 ± 6·9	ND	99 ± 10·6

FEV1, flow expiratory volume in one second; DLCO, diffusion lung carbon monoxide; TLC, total lung capacity – percent prediction; ND, not done.

^*P = 0·03 FEV1 CD versus SA and 0·037 SA versus C0

^†P = 0·007 DLCO SA versus CRD.
