The magnitude of the placebo response: the difference between P and NH (i.e., P-NH). It is a matter of interpretation whether the value of P-NH indicates the efficacy of the entire treatment process or the magnitude of the "placebo response". The results of these comparisons then determine whether or not a particular drug is considered efficacious.

For example in a study released by the British Medical Journal, in 1995 studying the effects of strict blood pressure control versus more relaxed blood pressure control in diabetic patients, the clinical control group was the diabetic patients that did not ...
Experimental investigations should always be compared against the best methods, but under certain circumstances a placebo or no treatment group may be utilized (Article 29).
