  • First part: Adjusted HRs (aHRs) for pneumonia hospitalisation or all-cause mortality for outpatients with acute exacerbations of chronic obstructive pulmonary disease who were treated with a long-course oral corticosteroid (OCS) treatment during the 1-year follow-up. Second part: aHRs where we are not counting for any events before day 30. The reference group was the short-course OCS treatment. All analyses were adjusted for age, sex, inhaled corticosteroids, smoking status, calendar year, FEV1% predicted, Medical Research Council Dyspnoea Scale, body mass index, heart failure, atrial fibrillation, myocardial infarction, hypertension, diabetes mellitus, peripheral vascular disease, cerebrovascular disease, renal failure and depression.
