About the study

ADDITION-DK includes randomised studies comparing routine treatment with more intensive treatment and cohort follow-up studies, and a total of 175 practices from five Danish regions participate in the study.

All 163,189 patients aged 40-69 years listed with these practices were invited to take part in a stepwise screening programme for diabetes. The first step was to complete a score questionnaire. People with a high screening score (indicating increased risk of type 2 diabetes) were requested to consult their general practitioner. Almost 28,000 people consulted their general practitioner and had blood samples taken.
