A retrospective study looked at data from the General Practice Research Database comparing the incidence of myocardial infarction in patients who were prescribed a new inhaler licensed for Chronic Obstructive Airways Disease with the incidence of myocardial infarction in patients who were matched for age and sex only and of course were not prescribed this medication. They found a relative risk of 1.35 (confidence intervals 1.12 to 1.51) for patients taking the drug.
Select from the list the single valid conclusion from the study.
