Blinding is a procedure in which one or more parties in a trial are kept unaware of which treatment arms participants have been assigned to, in other words, which treatment was received. Blinding is an important aspect of any trial done in order to avoid and prevent conscious or unconscious bias in the design and execution of a clinical trial.

A clinical trial is called single blind when only one party is blinded, usually the participants. If both participants and study staff are blinded, it is called a double blind study. Triple blinded studies also extend blinding to the data analysts. A trial in which no blinding is used and all parties are aware of the treatment groups is called open label or unblinded.
