Data are presented as the mean ± SD and n (%). Statistically significant (p < 0.05) values are indicated in bold. Univariate p-values were calculated using two-sample t-test, Mann–Whitney U-test, or Chi-squared test. UPDRS, unified Parkinson’s disease rating scale; H-Y, Hoehn and Yahr; MMSE, Mini-mental state examination; MoCA, Montreal Cognitive Assessment; HAMD, Hamilton Depression Scale; HAMA, Hamilton anxiety scale; PDSS, Parkinson disease sleep scale; NMSQuest, non-motor symptoms questionnaire.
