Table 2. Logistic regression model showing variables associated with relapse status.

Variable	OR	95% CI	p-value
ESR >20 mm/h	2.45	1.10–5.46	0.023
CRP ≥5 mg/L	1.95	0.98–4.22	0.056
TNF-a inhibitor	4.87	1.70–13.90	<0.001
Cyclosporine	3.85	1.48–10.03	0.006
Azathioprine	-	-	0.494(no relapses observed)
Age	0.98	0.93–1.03	0.398
Surgical intervention	1.55	0.82–2.91	0.184
ACE >52 U/L	2.26	1.12–4.53	0.010

TNF-a inhibitors and cyclosporine were used as rescue therapy in relapsing/refractory cases; therefore, their statistical associations with relapse should be interpreted cautiously due to confounding by indication, TNF-a: Tumor necrosis factor alpha; OR: Odds ratio; CI: Confidence interval; ESR: Erythrocyte sedimentation rate; CRP: C-reactive protein
