Derived and reuseable data

Derived and reuseable data#

Last modified: 21 Feb 2025

All UK LLC researchers are asked to make their research outputs available to others in the TRE. Reusable data are stored in the RETURNED DB schema, and can be requested via the Selection process in UK LLC Explore.

Datasets created by researchers
Documentation and syntax are available in UK LLC’s GitHub Repository. There should be sufficient information in GitHub to determine whether a derived dataset is sufficient for your purposes. Derived datasets are only available in the TRE and can be requested via Explore under the RETURNED section.

Datasets created by UK LLC
UK LLC has created harmonised datasets to facilitate research using multiple LPS. Harmonised variables currently include sex, gender, ethnic group, age, educational attainment, and COVID-19 diagnoses. These have been derived from LPS (self-reported) data, but will be expanded to include linked data. These datasets can be requested from the RETURNED schema in Explore.

The future
As more returned datasets, and reuseable syntax, become available in the TRE, they will be documented in this Guidebook.
