Table 4.

Predictors of inactive disease after newly initiating treatment with TNF-α inhibitor. Odds ratios less than 1 signify decreased odds of attaining inactive disease.

Outcome	Predictors	Univariate Odds Ratio	Multivariable model Odds Ratio
Inactive disease at 1 year follow-up	ERA (vs RF-poly)	0.23 (0.07 – 0.84)	0.20 (0.07 – 0.56)
	Baseline CHAQ < 1	4.1 (1.4 – 13)	5.7 (1.7 – 19)
	Active enthesitis	0.36 (0.13 – 0.96)	------
Inactive disease ever	ERA (vs RF-poly)	0.24 (0.07 – 0.82)	0.24 (0.08 – 0.75)
	Baseline CHAQ < 1	2.8 (1.2 – 6.7)	6.0 (1.6 – 23)
	Normal ESR at baseline	0.43 (0.17 – 1.1)	------
	Active enthesitis	0.43 (0.20 – 0.95)	------
	Number of follow-up visits	1.4 (1.1 – 1.7)	1.5 (1.1 – 2.1)
