When you delete groups from a trial, you delete them from the system, and can not recover them. If you delete a record accidentally, follow the instructions in Adding Sub-Groups to add it back.
How to Delete Sub-groups
Search for the trial of interest. For instructions, refer to Searching for Trials in PA.
In the search results, click the NCI Trial Identifier link for that trial. The Trial Identification page appears.

On the Scientific Data menu, click Sub-groups. The Sub-group page appears.
- In the Delete column for the appropriate record, click the Delete icon.
