Baseline characteristics of early PsA patients associated by univariate and multivariate analysis with total delay

Total delay	Univariate model		Multivariate model
	OR (95% CI)	P value	OR (95% CI)	P value
Female sex	1.57 (1.17 to 2.12)	0.003	1.44 (1.03 to 2.02)	0.034
Chronic back pain <45 years	1.90 (1.39 to 2.60)	<0.001	1.71 (1.21 to 2.42)	0.003
Swollen joint count	0.95 (0.91 to 0.98)	0.005
Enthesitis	1.75 (1.30 to 2.37)	<0.001	1.53 (1.08 to 2.17)	0.016
CRP	0.98 (0.96 to 0.99)	0.002	0.98 (0.97 to 0.99)	0.006

Patient characteristics associated with total delay were analysed using logistic regression by creating two groups based on the median value of total delay.

CRP, C-reactive protein; PsA, psoriatic arthritis.
