A dichotomous dependent variable of EEG alpha coherence in the left frontoparietal electrode pair was assigned a value of 0 when coherence was <0.5 and 1 when coherence was ≥0.5.
BADS: Behavioral Assessment of the Dysexecutive Syndrome; HY stage: Hoehn and Yahr stage; B: regression coefficient; SE: standard error; 95% CI; 95% confidence interval.
∗Statistically significant (p < 0.05).
