  1. Data are shown as n (%) or the mean (standard deviation).
  2. The presence of orthostatic symptoms was defined as a score of ≥1 on any of items 14 to 16 of the SCOPA-AUT.
  3. The severity of orthostatic symptoms was defined as the sum of scores from items 14 to 16 of the SCOPA-AUT.
  4. LMM low muscle mass, NMM normal muscle mass, SCOPA-AUT Scales for Outcomes in Parkinson’s Disease–Autonomic Dysfunction.
