Randomized Placebo-Controlled Placebo Trial to Determine the Placebo Effect Size.

The present study indicated that true placebo effect sizes can be analyzed through a proper IPRCT design, and instead of treating high numbers of patients with placebos in a RCT, which increases the risk for subjects not receiving the active treatment, the I PRCT technique seems to be much more appropriate to analyze the effect sizes of any active treatment.
