Acupuncture is little more than a theatrical placebo! If we confront an acupuncture fan with this statement, he/she is bound to argue that there are some indications for which the evidence is soundly positive. One of these conditions, they would claim, is nausea and vomiting. But how strong are these data? A new study sheds some light on this question.
The objective of this RCT was to evaluate if consumption of antiemetics and eating capacity differed between patients receiving verum acupuncture, sham acupuncture, or standard care only during radiotherapy. Patients were randomized to verum (n = 100) or sham (n = 100) acupuncture (telescopic blunt sham needle) (12 sessions) and registered daily their consumption of antiemetics and eating capacity. A standard care group (n = 62) received standard care only.
The results show that more patients in the verum and the sham acupuncture group did not need any antiemetic medications, as compared to the standard care group after receiving 27 Gray dose of radiotherapy. More patients in the verum and the sham acupuncture group were capable of eating as usual, compared to the standard care group. Patients receiving acupuncture had lower consumption of antiemetics and better eating capacity than patients receiving standard antiemetic care, plausible by nonspecific effects of the extra care during acupuncture.
The authors concluded that patients receiving acupuncture had lower consumption of antiemetics and better eating capacity than patients receiving standard antiemetic care, plausible by nonspecific effects of the extra care during acupuncture.
I find these conclusions odd because they seem to state that acupuncture was more effective than standard care. Subsequently – almost as an afterthought – they mention that its effects are brought about by nonspecific effects. This is grossly misleading, in my view.
The study was designed as a comparison between real and sham acupuncture, and the standard care group was not a randomised comparison group. Therefore, the main result and conclusion has to focus on the comparison between verum and sham acupuncture. This comparison shows that the two did not produce different result. Therefore, the study shows that acupuncture was not effective.
A much more reasonable conclusion would have been: THIS STUDY FAILED TO FIND SIGNIFICANT EFFECTS OF ACUPUNCTURE BEYOND PLACEBO.
