Foot and ankle characteristics associated with falls in adults with established rheumatoid arthritis: a cross-sectional study

Table 4 Stepwise logistic regression analyses comparing fallers (n = 119) and non-fallers (n = 82) on all predictor variables adjusting for age^a

	Odds ratio (95 % confidence interval)	P value
Age	0.99 (0.96-1.02)	0.500
Vascular disease	3.22 (1.17-8.88)	0.024
Peak plantar pressure midfoot	1.12 (1.00-1.25)	0.046
(for each 20kPa increase)	1.12 (1.00-1.25)	0.046
Foot Impairment FIS_AP	1.17 (1.05-1.31)	0.005
(for each 3 point increase)	1.17 (1.05-1.31)	0.005
