Interpretation Introduction

Interpretation:The statement that explains the double-blind study should be explained.

Concept Introduction: A common way to test a new drug is the double-blind test. In such a test,half of the patients are given the actual drug and the other half of them are given a placebo. But neither the doctors nor the patients know who have received what. Sometimes patients who received a placebo may experience positive results because they thought they are getting the actual drug.
