For studies that use randomization, Clinical Studio allows study builders to dictate form logic according to where subjects are randomized. For example, each subject's randomization assignment can dictate if specific intervals, forms, or fields are displayed.

After defining a randomization, the conditional action builder will display that randomization name as a constant. In the example shown here, a condition is being built on a field to hide the field if the subject is randomized into group 1. For group definitions, reference the randomization allocations.
