Significance of Placebo controlled trial
A placebo-controlled trial is a clinical research design that involves comparing the effects of an active treatment with a placebo, a non-active substance designed to resemble the treatment. This approach allows researchers to determine the true efficacy of the treatment by observing differences in outcomes between the two groups. Placebo-controlled trials are essential in clinical studies to ensure that any observed effects can be attributed to the treatment itself rather than psychological factors or other biases.
