Table 2

Logistic regression analysis to assess driving cessation.

Variable	Model 1		Model 2
	OR (95% CI)		OR (95% CI)
Disease duration (per 1-year increase)	1.11 (0.92–1.21)	0.112	1.10 (0.96–1.44)	0.221
Freezing of gait (freezing of gait was present)	35.68 (4.42–833.32)	<0.001	14.46 (1.91–303.74)	0.008
Attention (per 1 point increase)	0.58 (0.29–1.09)	0.090	0.75 (0.35–1.53)	0.427

Model 1: each variable is adjusted for age. Model 2: multivariate analysis was performed by variables with in the univariate analysis. OR: odds ratio; CI: confidence interval.
