Answer 1

Ans.

clinical trial--

The World Health Organization (WHO) definition for a clinical trial is. 'any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects on health outcomes'.

They are the primary way that researchers find out if a new treatment, like a new drug or diet or medical device (for example, a pacemaker) is safe and effective in people. Often a clinical trial is used to learn if a new treatment is more effective and/or has less harmful side effects than the standard treatment.

Clinical trials are important for discovering new treatments for diseases, as well as new ways to detect, diagnose, and reduce the chance of developing the disease. ... Clinical trials also help doctors decide if the side effects of a new treatment are acceptable when weighed against the potential benefits.

Possible benefits of clinical trials include the following: Participants have access to new treatments. ... Participants who are not in the group receiving a new treatment may receive the standard treatment for the particular condition, which may be as good or better than the new approach.
