12. Main objective(s)
What is the main objective of the study?
To describe trends in patterns of utilisation of rosiglitazone-containing preparations over time in response to risk minimsation events (switches to and from rosiglitazone-containing preparations);
To examine prevalence of ontraindicated and offlabel use;
To examine risk of acute drug reactions after risk minimisation
To examine changes in objective parameters of disease in medication switchers

Will patients be followed up?Yes
Please describe duration of follow up
Up to 6 months after medication switch
15. Data analysis plan
Please provide a brief summary of the analysis method
1.Descriptive drug utlization patterns according to calendar time
