The Availability of a Data-Field indicates whether it is available for use by researchers. There are two categories:
- Available - data can be requested by researchers;
- Preview-Only - data cannot yet be requested, however a preview of its properties is shown.
UK Biobank holds additional data (particularly participant identities) which will never be made available to researchers and hence is not listed in the Showcase. Some available data, marked as sensitive, is only made available under special circumstances.
