What does participation mean for me?
Participation is completely voluntary. If you take part in HELIUS, we will ask you to fill in a questionnaire at home, and we will make an appointment with you for the physical examination at one of our locations. You will receive a free OV-chipkaart (public transport card) to travel to and from the location. A few weeks after your visit, your personal results will be sent to your home address, together with a short explanation. We will also send these results to your general practitioner (GP). If you do not want your results to be shared with your GP, you will not be able to participate in this study.
