†Missing data: age, age at diagnosis of Parkinson disease, duration of Parkinson disease and residence type had < 4.0% missing data; body mass index was missing for 53.0% of patients; smoking status was missing for 57.1%.
‡Significance by sex defined as p < 0.05 using t test and χ2 of independence test.
§Column percentage is > 100% because patients could have more than 1 chronic condition.
