Comment on “Analysis and Thoughts about the Negative Results of International Clinical Trials on Acupuncture”

الملخص EN

[1] acupuncture studies showing negative results, when conducted outside China, must be wrong.

Apparently, acupuncture trials rarely, if ever, produce negative results in China because acupuncture is always performed correctly by experts.

Is this true or could it be the case that bias is endemic in clinical trials of acupuncture in China?
