Data are expressed as number of patients.
BADS: Behavioral Assessment of the Dysexecutive Syndrome; ED: executive dysfunction; PD: Parkinson’s disease.
ED was defined as age-controlled standardized BADS score <70.
The low coherence group had coherence <0.5 and the high coherence group had coherence ≥0.5.
The relation between two coherence groups and ED was assessed using Fisher’s exact test. Statistically significant ().
