📊 Outcome Comparison
Cost-Effectiveness Ratio
This study showed that acupuncture at specific points of the Shaoyang meridian is more effective and economical for preventing migraine than other types of acupuncture. Patients treated with this technique had nearly 4 fewer migraine days per month and spent less money on treatment.
Article summary
Plain-language narrative summary
This Chinese multicenter study represents an important contribution to understanding the economic efficacy of acupuncture in migraine treatment. Conducted between April 2008 and December 2009 in four Chinese cities, the randomized clinical trial involved 480 participants with a migraine diagnosis of at least one year, with a minimum frequency of two attacks per month. The primary objective was to compare the cost-effectiveness of different acupuncture approaches, with special focus on the comparison between specific points of the Shaoyang meridian versus penetrating sham acupuncture. The methodology involved randomization of participants into four distinct groups: acupuncture at specific points of the Shaoyang meridian (group A), nonspecific points of the Shaoyang meridian (group B), specific points of the Yangming meridian (group C), and sham acupuncture at non-points on the limbs (group D).
The treatment protocol consisted of 20 acupuncture sessions distributed over four weeks, using disposable needles. Participant follow-up extended for 16 weeks, with assessments performed at weeks 0, 4, 8, and 16. The economic analysis was conducted from a societal perspective, including direct and indirect costs. Direct costs encompassed acupuncture fees, medications, and exams.
Indirect costs were estimated based on workdays lost due to migraine attacks, using statistical yearbook data to estimate average daily wages. The primary outcome was the cost-effectiveness ratio, expressed as cost per day of migraine attack reduction from baseline to week 16. The results demonstrated clear superiority of the specific Shaoyang points group in terms of cost-effectiveness. The total cost per patient was ¥1,273.2 in the specific Shaoyang group, compared to ¥1,427.7 in the nonspecific Shaoyang group, ¥1,490.8 in the specific Yangming group, and ¥1,470.1 in the sham acupuncture group.
The mean reduction in migraine days was 3.97 days in the specific Shaoyang group versus only 2.16 days in the control group. Consequently, the cost-effectiveness ratios were 320.5 for specific Shaoyang, 401.6 for nonspecific Shaoyang, 393.1 for specific Yangming, and 682.2 for sham acupuncture. Quality-of-life analysis using the migraine-specific questionnaire (MSQ) revealed significant improvements in all three domains assessed in the specific Shaoyang group compared to the control group. Sensitivity analysis confirmed the robustness of the results, even with variations of 10-20% in acupuncture fees.
The clinical implications are substantial, providing solid scientific evidence for the economic superiority of careful selection of acupuncture points based on meridian theory. The study validates fundamental principles of traditional Chinese medicine that postulate greater efficacy of genuine points compared to non-points.

▸ Clinical Relevance
Preventive management of migraine is still a poorly resolved clinical problem in pain clinics in Brazil: a significant portion of patients does not tolerate or responds inadequately to conventional oral preventives, and the discussion about cost-effectiveness of nonpharmacologic therapies rarely reaches the office with quantitative data. This multicenter trial with 480 participants fills a gap by demonstrating that acupuncture with specific points on the Shaoyang meridian, in addition to being clinically superior, has a cost-effectiveness ratio of 320.5 versus 682.2 in the sham group—less than half the cost per attack day avoided. For the physician treating migraine patients with two or more monthly attacks who seeks to justify incorporating acupuncture into the therapeutic plan, these data from a societal perspective—including workdays lost—make the argument much more concrete and defensible to health managers and insurance providers.
▸ Notable Findings
The most noteworthy finding is not the efficacy of acupuncture per se, but the magnitude of the difference between specific and nonspecific points within the same meridian. The specific Shaoyang group reduced migraine days by 3.97, while the nonspecific group reduced them by only 2.21—a difference that is not clinically trivial and suggests that precise point selection carries therapeutic value independent of the nonspecific neuromodulatory effect of the needle. Another relevant data point is that even the specific Yangming group, technically well conducted, had inferior economic performance compared to specific Shaoyang, reinforcing that the correspondence between the patient's clinical pattern and the meridian treated matters. The improvement in the three MSQ domains in the specific Shaoyang group adds a functional dimension that goes beyond the count of attack days.
▸ From My Experience
In my practice in the pain clinic, I have observed that patients with high-frequency episodic migraine—those at the threshold of chronification, with six to ten monthly attacks—are the ones who benefit most from acupuncture as an adjuvant preventive. I usually see perceptible response from the third or fourth week of treatment, which corresponds to about fifteen sessions within an initial intensive protocol. The data from this study, with a protocol of 20 sessions over four weeks, is more compressed than what I usually practice—I prefer to distribute over six to eight weeks—but the logic of consolidating the effect before spacing is the same. I frequently combine with pain neuroscience education, cervical postural adjustment, and, when there is an associated cervical trigger point component, I alternate dry needling of suboccipital points. Patients with purely hormonal migraine or with frequent aura tend to respond more unpredictably, and in these cases I maintain pharmacologic preventive in parallel while we assess response in the first eight sessions.
