What is evidence-based medicine?
Evidence-based medicine postulates that a drug, a method of treatment, a diagnostic method can be used only when it has proven its feasibility. One of the main principles of evidence–based medicine is the so-called "blinding" of research. At the same time, neither the patient himself, nor the doctor, nor the statistician who calculates the result, do not know what the patient receives: a drug or a placebo.
