Glutathione as a Biomarker in Parkinson’s Disease: Associations with Aging and Disease Severity

Table 3

High versus low blood Glu concentrations in PD. In order to evaluate whether blood Glu may be associated with rate of progression, regression analysis is adjusted for age and years since PD diagnosis.

High versus low blood Glu in Parkinson’s disease severity
	GSH < 1000 μmol/L	GSH ≥ 1000 μmol/L	(95% CI)
Unified PD Rating Scale (UPDRS)	75.82 (12.19)	65.9 (10.33)	0.087 (−11.90, 0.83)
Patient-Reported Outcomes in PD (PRO-PD)	1013.46 (365.37)	675.53 (381.57)	0.012 (−525.28, −67.49)
