The randomized clinical trial.
Abstract
Randomized clinical trials were developed to eliminate biases inherent in clinical medicine. Six types of bias that can occur during patient selection and treatment allocation and in the collection and analysis of the data have been identified. A variation of the prospective randomized clinical trial, the nonrandomized surgeon design, overcomes biases specific to surgical investigations.
