Open-label
Everyone knows which treatment is being given — nothing is hidden.
What it means
An open-label study is one where both the participant and the study team know exactly which treatment the participant is receiving.
Why it matters if you take part
You will know what you are getting. This is the most common arrangement in trial records, and it is often used when hiding the treatment would be impractical or unsafe.
What it looks like in practice
The registry record will say "Masking: NONE".
