For a particular variable, values with different superscripts indicate a statistically significant difference. PD: Parkinson’s disease; MDS-UPDRS: Movement Disorder Society-Unified Parkinson’s Disease Rating Scale; SCOPA-AUT: Scale for Outcomes in Parkinson’s Disease-Autonomic; SBR: Specific binding ratio; LEDD: levodopa equivalent dose.
