single-blind
adj1
Describing an experiment (usually medical) in which some information which might influence the trial is withheld from particular participants until the experiment is complete. Most commonly, information about treatment groups is withheld from subjects, but not the administrators.
- By definition, a single-blind study is the one in which either the patient or investigator is blind to the assignment of the patient. In practice, a single-blind trial is referred to as a trial in which only the patient is unaware of his or her treatment assignment.2004, Shein-Chung Chow, Jen-Pei Liu, Design and Analysis of Clinical Trials: Concepts and Methodologies, 2nd edition, John Wiley & Sons, →ISBN, page 160:
