Table 1.

Demographic and clinical information for all study participants at baseline (PD: n = 30; HC: n = 15) and for the PD subgroup at baseline and 19.9 ± 3.8 months follow-up (PDFU: n = 15). Independent-samples t-test was used to assess the difference between PD and healthy controls at baseline. For the PD follow-up group, Wilcoxon signed-rank and paired-samples t-test were used to assess the difference between baseline and follow-up.

LED = L-dopa equivalent dose (mg).

UPDRS = Unified Parkinson’s disease rating scale.

The UPDRS and H&Y scale were assessed in the practically defined off-medication state.
