Hotfix released for v6 & v7 CDRs

  • Updated

The All of Us Researcher Workbench team released hotfixes for the All of Us Controlled Tier (CT) v7 Curated Data Repository (CDR) on 12/5/2023 and the CT v6 CDR for 1/22/2024 to ensure consistency with data privacy protections regarding a participant’s date of birth (DOB).

As a result of the hotfix, relevant records from select participants were removed from the following datasets:

  • v7 Controlled Tier CDR 
  • v6 Controlled Tier CDR

For researchers with ongoing active projects using either of these CDR versions, we recommend that you re-run any of your notebooks as these changes may impact your analysis. 

The changes are reflected in the data dictionaries as well as release notes.

If you have any questions regarding the hotfix, please contact us at
