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.
