Univariate linear correlations between the baseline and clinical characteristics with Parkinson’s disease summary index (PDSI) of the health-related quality of life (HRQoL) (n = 157).

PIGD: postural-instability-gait-difficulty; FOSS: freezing-speech-swallowing
* Statistical significant correlation (two-tailed p-value<0.05)
1 Total number of comorbidities
2 Score A is the sum of UPDRS-Part III items concerning facial expression, tremor, rigidity, and Bradykinesia which are considered relatively L-dopa responsive
3 Score B is the sum of UPDRS-Part III items concerning speech and axial impairment (arising from chair, posture, postural stability, gait) which are considered relatively L-dopa non-responsive.
