The idea
Knowing which group a participant is in can change how they behave and how they are treated, so studies keep participants and clinicians unaware of the allocation.
In practice
A trial in which neither the participant nor the person delivering care knows.
Where people slip
Blinding is not always possible. Where it is impossible, the risk it would have controlled is still present and should be stated.
