Generate a randomization list
Create a randomization list for Testing mode when you're ready to test data entry and randomization. Create a randomization list for Production and Training mode when you're ready to make the study live.
Tip:
To prevent potential unblinding, create separate lists for each mode. If a statistician provides only the production list for a study, upload it in Production mode and generate lists for Testing and Training modes.We recommend you first create a randomization list in Testing mode before you create one in Training or Production mode.
Do you want to upload a randomization list, instead of generating one? See Upload a randomization list.
We recommend using dynamic block assignments. However, if you are doing static block assignments with a generated randomization list, you must assign blocks of randomization numbers to each site, country, or region. For more details, see Assign blocks of randomization numbers to a site, country, or region.
To view or manage generated randomization lists, the list associated with study version, or the generated Randomization Seed, select Manage from the Randomization List drop-down. The Randomization Seed number is displayed as read only on the Randomization Lists column under the name of the randomization list it duplicated. Revert to the old randomization list by manually unassigning the study version.
You can generate or upload a new randomization list at any time, without creating a new version of a study.
