Approved Studies

Studies requesting data from the OPC Research Database must undergo protocol approval via ADEPT before any data access is granted. ADEPT is an independent body of experts who ensure the database is only utilised as part of projects that adhere to high standards of confidentiality, scientific rigour, and ethical integrity.

 

Below is an index of protocols approved to use the OPCRD. Filter by year in the right-hand column and click on protocols for further information (coming soon).

 

Following publication, peer-reviewed articles using OPCRD data are listed on our publications page.
