Case-control study of factors that trigger inflammatory bowel disease flares

Table 2 Disease indices in patients with a disease exacerbation (flares) and those in remission (controls)

Disease indices	Flares	Controls	P value
Average CDAI score (CD)	349.8 ± 161.2	69.0 ± 52	< 0.0001
Average full Mayo score (UC)1	7.55 ± 2.9	1 ± 1.1	< 0.0001
Average partial Mayo score (UC)1	5.41p ± 1.8	0.1p ± 0.3	< 0.0001
C-reactive protein (mg/dL) (normal 0-1.0)	3.48 ± 5.5	1.19 ± 1.7	0.0002
ESR (MM/HR) (normal 0-30)	29.9 ± 25.6	16.6 ± 17.5	0.001
Albumin (g/dL) (normal 3.0-5.0)	3.40 ± 0.7	3.85 ± 0.4	< 0.0001
Hemoglobin (g/dL) (normal 11.5-15.3)	13.1 ± 2.1	14.3 ± 1.6	0.0005

¹One of two values for Mayo score per patient, patients had either full score (n = 19) or partial score (n = 51) depending on whether the patient had sigmoidoscopy. ESR: Erythrocyte sedimentation rate. CDAI: Crohn's Disease Activity Index; CD: Crohn’s disease; UC: Ulcerative colitis.
