When configuring a randomization, you can define how treatment arms are displayed using the blinding model.
Blinding models
Open / Single-blind – The assigned arm is visible to site users with access to the randomization list.
Double-blind – The assigned arm is hidden. Only users with the Unblind Access permission can view it.
To control who can configure, view, or unblind randomizations, permissions must be set at the role level.
