title: Controlled trials: nuisance or necessity?
abstract: Placebos can mimic in many ways the characteristics of active drugs. The importance of placebo controls in clinical trials in the evaluation of therapeutic efficacy and side action liability of drugs is exemplified by specific examples from human experimentation. It is concluded that controlled trials will prevent many of the errors inherent in uncontrolled therapeutic observations.
