Table 4 Independent variables determinants AFC (n = 413)

Predictive variable	Univariate analyses^a	Multivariate analyses^b	Exp (B) Adjusted odds ratio (CI 95%)^c	p
Hospital site	Proportions similar AFC versus NAFC according to hospital site	Excluded from model
Gender	p = 0.04	Included in model	1.72 (1.06–2.88)	0.03
Age	p = 0.01	Included in model	1.02 (1.00–1.04)	0.02
Social deprivation	p = 0.363	Excluded from model
Disease duration	p= > 0.001	Included in model	1.04 (1.02–1.07)	< 0.01
Arthritis medications	Proportions similar AFC versus NAFC according to arthritis medications	Excluded from model
Disability (HAQ)	p = 0.005	Exclude from model, as 1 section captures lower limb disability

^aUnivariate analyses of demographic and clinical variables to identify factors associated as predictors of AFC
^bVariables with p = < 0.2 in univariate analyses were entered into a series of logistic regression models to identify independent predictors of AFC
^cCI 95% Confidence Interval
