[[Placebo]]-[[controlled]] studies are a way of testing a medical therapy in which, in addition to a group of subjects that receives the treatment to be evaluated, a separate control group receives a sham "placebo" treatment which is specifically designed to have no real effect. Placebos are most commonly used in [[blinded]] trials, where subjects do not know whether they are receiving real or placebo treatment. Often, there is also a further "natural history" group that does not receive any treatment at all. placebo-controlled_study.txt Last modified: 2024/06/07 02:55by 127.0.0.1
