Single-blind
One side — usually the participant — does not know which treatment is which.
What it means
In a single-blind study, one group of people involved is kept unaware of the treatment assignment. Most often that is the participant, while the study team knows.
Why it matters if you take part
It reduces the chance that knowing your assignment changes how you report your symptoms, while still letting the team manage your care with full information.
