I want to know the answer to the following question:
What did an analysis of the 13 studies of pain treatment conclude about the effect of real treament versus sham treatments?
All the background I'm provided with is that "An analysis of the 13 highest quality studies of pain treatment with acupuncture, published in January 2009, concluded there is little difference in the effect of real, sham and no acupuncture.". Is that enough to answer the question?
Answer: yes
