Table 3 Multivariate analysis of predictive factors of clinical response to granulocyte-monocyte apheresis: Steroid course and clinical activity index score at baseline

Independent variables	OR	95% CI	Wald	P-value
Steroid course	0.390	0.176-0.865	5.361	0.016
4 < CAI < 8	0.770	0.425-1.394	3.747	0.028
CRP (mg/dL)	0.908	0.381-2.166	0.047	0.828
ESR (mm/h)	0.965	0.491-1.896	0.011	0.917
Location of disease (Left side/pancolitis)	0.822	0.462-1.462	0.446	0.504
Duration of disease > 120 mo	1.089	0.485-2.466	0.043	0.836

CAI: Clinical activity index; ESR: Erythrocyte sedimentation rate; CRP: C reactive protein; OR: Odds ratio; CI: Confidence interval.
