Randomized A randomized controlled trial is the study design that can provide the most compelling evidence that the study treatment causes the expected effect on human health.

    Randomization in Clinical Trial Studies David Shen, WCI, Inc. Zaizai Lu, AstraZeneca Pharmaceuticals ABSTRACT Randomization is of central importance in clinical trials. It prevents selection bias and insures against accidental bias. It produces comparable groups, and eliminates the source of bias in treatment assignments.

    Many different types of people take part in clinical trials. Some are healthy, while others may have illnesses. Research procedures with healthy volunteers are designed to develop new knowledge, not to provide direct benefit to those taking part. Clinical trials are a kind of clinical research designed to evaluate and test new interventions such as psychotherapy or medications. Clinical trials are often conducted in four phases. The trials

A small group of patients are enrolled in the first stage; and the enrollment of another group of patients in stage 2 is “conditional” on the outcome of the first group. The activation of the second stage depends on an In epidemiology, controlled clinical trial or community trial with random distribution. The researcher manipulates the research conditions and randomly distributes the groups. The objective of experimental studies is to estimate the efficacy of a preventive, curative or rehabilitative intervention.
