Multivariate risk analysis for SCOPA-AUT and orthostatic hypotension.

SCOPA-AUTa	B	P	Orthostatic hypotensionb	B	P	OR	95% CI
							Lower	Upper
Constant	3.41	0.500	Constant	−2.30	<0.001	0.100
Subtypes	−4.71	<0.001	Subtypes	1.86	0.005	6.452	1.735	23.988
UPDRS-III	0.15	0.010
Duration	0.59	0.001

Covariates are subtypes, gender, age, age at onset, duration, LEDD, and UPDRS-III. CI, confidence interval; LEDD, L-dopa equivalent daily dosage; OR, odds ratio; PD, Parkinson's disease; PIGD, postural instability gait disorder; SCOPA-AUT, scales for outcomes in PD-autonomic symptoms; TD, tremor dominant; UPDRS, unified Parkinson's disease rating scale.

^aAnalyzed by multiple linear regression.

^bAnalyzed by binary logistic regression. OR value refers to PIGD vs. TD.
