The Quality of Methodological and Reporting in Network Meta-Analysis of Acupuncture and Moxibustion: A Cross-Sectional Survey.
Yuan, Ting, Xiong, Jun, Wang, Xue et al. · Evidence-based complementary and alternative medicine : eCAM · 2021 · DOI
Quick Summary
This study reviewed 29 research papers that used a statistical method called network meta-analysis to compare different acupuncture and moxibustion treatments. The researchers assessed how well these papers were designed and reported their findings. They found that most papers had medium quality, with some having significant gaps in how they explained their methods and results.
Why It Matters
This quality assessment is relevant to ME/CFS patients because chronic fatigue syndrome was among the conditions studied in these acupuncture network meta-analyses. Understanding the reliability and transparency of research methodology helps patients and clinicians evaluate the trustworthiness of evidence before considering acupuncture as a treatment option.
Observed Findings
- Only 1 of 29 network meta-analyses met high-quality criteria; 24 were medium quality and 4 were low quality based on AMSTAR2 assessment.
- Mean PRISMA-NMA reporting score was 23.62 out of 29, with 8 specific reporting domains showing severe flaws (protocol registration, search strategy, data collection process, data items, additional analyses, risk of bias assessment, and results reporting).
- Acupuncture and moxibustion network meta-analyses addressed 23 different conditions, with knee osteoarthritis and primary dysmenorrhea each covered in 3 separate analyses.
- The 29 reviews collectively analyzed 1,098 clinical trials involving 4–22 different intervention types per review.
Inferred Conclusions
- The acupuncture and moxibustion network meta-analysis field remains in an early developmental stage with overall moderate methodological and reporting quality.
- Systematic reporting and methodological gaps exist across many reviewed studies, limiting confidence in the validity and applicability of their findings.
- Future acupuncture research requires stronger adherence to quality standards and transparent reporting protocols before conclusions can be considered reliable.
Remaining Questions
- What is the actual clinical efficacy of acupuncture for chronic fatigue syndrome and other conditions based on higher-quality network meta-analyses?
- How do methodological limitations in these reviews affect the reliability of specific treatment recommendations for ME/CFS patients?
What This Study Does Not Prove
This study does not evaluate whether acupuncture is actually effective for ME/CFS or any other condition—it only assesses the quality of the research methodology and reporting. It also does not establish causation; rather, it identifies methodological weaknesses that limit confidence in conclusions drawn by previous studies. The presence of medium-quality studies does not confirm or refute any acupuncture treatment claims.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
