Ethics approval and consent to participate

The Institutional Ethics Review Board of the Erasmus MC reviewed the study protocol and provided an exemption from formal ethical assessment (MEC-2015-306), based on the non-interventional design. The study was carried out in accordance with the current ethical guidelines for epidemiological research.
