Active phase (n = 30)	104.67 ± 26.51a	0.025 ± 0.002a	5.83 ± 0.17a	0.002 ± 0.001a	0.41 ± 0.08a
Quiescent phase (n = 30)	32.69 ± 11.42a,b	0.004 ± 0.001a,b	2.06 ± 0.20a,b	0.006 ± 0.002a,b	0.65 ± 0.11a,b

^aP < 0.05 vs the normal control group.

^bP < 0.05 vs the active Crohn’s disease group.

r = 0.917 for intestinal peroxisome proliferator-activated receptor gamma 2 expression; r = -0.926 for intestinal occludin protein expression. CrF: Creeping fat; CD: Crohn’s disease; PPARγ2: Peroxisome proliferator-activated receptor gamma 2.
