| Parkinsonism | 958 | 473 | 485 | 1.01 (0.89–1.15) |
Note: CI = confidence interval, COPD = chronic obstructive pulmonary disease. *The probability of each comorbid condition was modelled, with hypertension (yes/no) as the predictor, along with age and sex. Example: Patients with hypertension were 1.69 times as likely to have diabetes as patients without hypertension.
