Please note that with respect to the GDPR, information about co-owners cannot be found in this open access data dictionary. In time, the data dictionary will be coupled to a new data request application system. As soon as this coupling is a fact, co-owners will be informed automatically after a data request has been submitted to The Maastricht Study. Until then, you can contact The Maastricht Study management team (um-researchdms@maastrichtuniversity.nl) for information on co-owners.
