PainSci commentary on Li 2012: ?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense.

This is a disturbing and typical example of sloppy modern acupuncture research, methologically flawed in several ways with clearly negative results, despite the fact that it was clearly built to give acupuncture an unfair advantage, by researchers who wanted to prove that acupuncture works. They concluded that acupuncture has only “a clinically minor effect on migraine,” damning with (very) faint praise, but even that is a biased exaggeration — cherry-picking the best results, and ignoring the more important negative ones. As summarized by Dr. Steven Novella for ScienceBasedMedicine.org: “Despite all of these shortcomings, all of which would bias the study in the direction of being positive, the study was negative. For the primary outcome measure there was no statistically significant difference between any of the acupuncture groups and the sham acupuncture group.”

BACKGROUND: Acupuncture is commonly used to treat migraine. We assessed the efficacy of acupuncture at migraine-specific acupuncture points compared with other acupuncture points and sham acupuncture.
METHODS: We performed a multicentre, single-blind randomized controlled trial. In total, 480 patients with migraine were randomly assigned to one of four groups (Shaoyang-specific acupuncture, Shaoyang-nonspecific acupuncture, Yangming-specific acupuncture or sham acupuncture [control]). All groups received 20 treatments, which included electrical stimulation, over a period of four weeks. The primary outcome was the number of days with a migraine experienced during weeks 5-8 after randomization. Our secondary outcomes included the frequency of migraine attack, migraine intensity and migraine-specific quality of life.
RESULTS: Compared with patients in the control group, patients in the acupuncture groups reported fewer days with a migraine during weeks 5-8, however the differences between treatments were not significant (p> 0.05). There was a significant reduction in the number of days with a migraine during weeks 13-16 in all acupuncture groups compared with control (Shaoyang-specific acupuncture v. control: difference -1.06 [95% confidence interval (CI) -1.77 to -0.5], p = 0.003; Shaoyang-nonspecific acupuncture v. control: difference -1.22 [95% CI -1.92 to -0.52], p < 0.001; Yangming-specific acupuncture v. control: difference -0.91 [95% CI -1.61 to -0.21], p = 0.011). We found that there was a significant, but not clinically relevant, benefit for almost all secondary outcomes in the three acupuncture groups compared with the control group. We found no relevant differences between the three acupuncture groups.
INTERPRETATION: Acupuncture tested appeared to have a clinically minor effect on migraine prophylaxis compared with sham acupuncture.
