Our Data Catalogue contains a full study description (Details tab) for each dataset and also provides access to online documentation (Documentation tab), resources (Resources tab) and access conditions (Access tab).
The Details tab provides information such as title, study number, PID, series, principal investigator, sponsors, contributors, topics, keywords, abstract, coverage and methodology, citation and copyright, the edition history, and the DOI.
The Documentation tab includes, for example, user guides that contain information on how to use the data, how the data were collected, and usually the original questionnaires or topic guides. Online variable lists provide the variable names and variable and value labels.
The Resources tab provides links to for example related studies and publications.
The Access tab contains information on the access conditions and provides online links.
