Multivariable Analysis of α-Synuclein-Positive Lesions in the ISLN, IX, and PSB-X Nerves in PD Patients With/Without Dysphagia

	Two-Factor Unadjusted^a Risk			Two-Factor Adjusted^b Risk
Variable	Odds Ratio	95% CI	P Value	Odds Ratio	95% CI	P Value
Absence/presence of dysphagia
Ref category: absence	64.5	(3.2, 1291)	0.0064	502.5	(4.6, 55102)	0.0095
Nerve type
ISLN vs. IX	21.3	(3.1, 149)	0.0020	45.8	(2.9, 717)	0.0064
ISLN vs. PSB-X	50.3	(5.9, 430)	0.0003	137.8	(7.5, 2535)	0.0009
IX vs. PSB-X	2.4	(0.8, 7)	0.1336	3.0	(0.8, 12)	0.1187

The two factors dysphagia and nerve type were not adjusted for patient characteristics.

The two factors dysphagia and nerve type were adjusted for PD duration, H&Y stages, and motor UPDRS.
