Add a region

You need to add regions to your study to be able to successfully randomize subjects. This procedure can also apply to rollover studies.

Do I have to do this? Only if you're using region-blocked randomization.

Want to see how to perform this task? Watch the video below.

1. Open the study settings.
2. Click the Study Settings tab.
3. On the top left, select a specific mode:
   • Production Settings
   • Testing Settings
   • Training Settings
4. In the Randomization Regions section on the right side pane, click Create Region.
5. In the Create Region dialog, enter a title for the region, such as Asia Pacific or Eastern Europe.
6. Select and expand the country to include in the region.

   If you want to define a region to include states only, expand a country to view its provinces and select those to be included in the region.

   Note:

   The same country is available to select in multiple regions but country states are only available to be added into one region.
   The country provinces are displayed.
7. Move the countries or provinces to the Selected States section by clicking the arrow icon ().
8. Select any of the following:
   • Save & Add Another to save and create another region.
   • Add to create the region and close the Create Region dialog.
   The regions are now displayed in the Selected States section along with their countries and states or provinces.
9. Create additional regions as needed for all modes.
