This systematic review was aimed at evaluating the effects of acupuncture on the quality of life of migraineurs.  Only randomized controlled trials that were published in Chinese and English were included. In total, 62 trials were included for the final analysis; 50 trials were from China, 3 from Brazil, 3 from Germany, 2 from Italy and the rest came from Iran, Israel, Australia and Sweden.

Acupuncture resulted in lower Visual Analog Scale scores than medication at 1 month after treatment and 1-3 months after treatment. Compared with sham acupuncture, acupuncture resulted in lower Visual Analog Scale scores at 1 month after treatment.

The authors concluded that acupuncture exhibits certain efficacy both in the treatment and prevention of migraines, which is superior to no treatment, sham acupuncture and medication. Further, acupuncture enhanced the quality of life more than did medication.

The authors comment in the discussion section that the overall quality of the evidence for most outcomes was of low to moderate quality. Reasons for diminished quality consist of the following: no mentioned or inadequate allocation concealment, great probability of reporting bias, study heterogeneity, sub-standard sample size, and dropout without analysis.

Further worrisome deficits are that only 14 of the 62 studies reported adverse effects (this means that 48 RCTs violated research ethics!) and that there was a high level of publication bias indicating that negative studies had remained unpublished. However, the most serious concern is the fact that 50 of the 62 trials originated from China, in my view. As I have often pointed out, such studies have to be categorised as highly unreliable.

In view of this multitude of serious problems, I feel that the conclusions of this review must be re-formulated:

Despite the fact that many RCTs have been published, the effect of acupuncture on the quality of life of migraineurs remains unproven.
