Stepwise logistic regression analysis of predictive factors of total Sharp score at 10 years

	Coefficient	SE	OR	95% CI
Constant	-1.085	0.513
Erosion score	1.729	0.588	5.64	1.78–17.86
After excluding the baseline radiographic scores from the model:
Constant	-1.345	0.631
ACPA	1.353	0.631	3.87	1.17–12.75
ESR	1.166	0.514	3.20	1.17–8.78

ACPA, anti-citrullinated protein antibody; CI, confidence interval; ESR, erythrocyte sedimentation rate; SE, standard error; OR, odds ratio.
