6500 residents in the Gran Duchy of Luxemburg, whether suffering from headache or not, were chosen randomly from the register of the General Inspectorate of Social Security to participate to the survey. All information and questionnaires were sent from the CRP-Santé.

A press conference was organised in the CRP-Santé to launch the Eurolight survey in Luxembourg: look here for more information and documents.
