Secondary data tables are the corpus of curated data we receive from national data warehouses for all eligible participants not belonging in a data restricting cohort and not registered in Northern Ireland, Wales or Scotland. They are mostly longitudinal in nature and agnostic to the recruited disease. Data at the point of release captures all activity contained in the period covered within each of the datasets up to the latest quarter published by NHSE and end of calendar year for PHE/NCRAS.

Please Note: The linking files MH_bridge and DID_bridge will no longer be provided as part of the main programme release. Participant id is already been included in all tables making these files redundant.
