Table 2

Multivariate logistic regression analysis of factors for PD patients with RLS.

Variables	Regression coefficient	OR value	95% CI	value
UPDRS III	0.031	1.032	0.982~1.084	0.212
PRBD	1.543	4.678	1.372~15.944	0.014
HAMD score	0.089	1.094	1.002~1.193	0.045
Daily LED	0.003	1.003	1.000~1.005	0.019

PD = Parkinson’s disease; RLS = restless leg syndrome; UPDRS III = unified Parkinson’s disease rating scale III; PRBD = probable rapid eye movement sleep behavior disorder; HAMD = Hamilton depression scale; daily LED = daily levodopa equivalent dose; tips for risk factor, in PRBD, daily LED, and the HAMD scores.
