The article presents an editorial about how to interpret results from surgical trials. The authors remark that it is important to distinguish between the effect of the intervention from the effect of the patient's expectation of the intervention when analyzing subjective outcomes in health care interventions. To avoid the placebo effect, it is necessary to ensure that patients do not know which treatment they are receiving. This randomization technique is not often practiced in surgical trials. The ethics underlying sham-controlled studies are discussed.
