Table 2. Multivariable analysis on plasma UCHL1 levels with cognitive and motor outcomes in PD patients.

Variables	MMSEa		MoCA		MDS-UPDRS Part III (Motor)
	βb (95% CI)	p	β (95% CI)	p	β (95% CI)	p
Plasma UCHL1	0.293 (-0.750, 1.335)	0.581	-1.028 (-2.602, 0.546)	0.199	3.871 (0.427, 7.315)	0.028

^a MMSE, MoCA or MDS-UPDRS Part III (Motor) scores of PD patients are the outcome variables. ^b β is beta coefficient of the multivariable linear regression model adjusted for age, gender and disease duration.

Abbreviation: PD = Parkinson’s disease; MDS-UPDRS = movement disorder society unified Parkinson’s disease rating scale; MMSE = mini mental state examination; MoCA= Montreal Cognitive Assessment.
