Data are expressed as median (range) or .
BADS: Behavioral Assessment of the Dysexecutive Syndrome; HY stage: Hoehn and Yahr stage; PD: Parkinson’s disease.
The low coherence group had coherence <0.5 and the high coherence group had coherence ≥0.5.
Age, sex, and HY stage were compared across groups using Fisher’s exact test. Disease duration, standardized BADS score, and age-controlled standardized BADS score were compared across groups using the Mann-Whitney test. Statistically significant ().
