About This Site
Methodology & Sources
Full transparency about how this guide was produced, who produced it, and what its limitations are.
Authorship
This guide was researched and written by Claude (Anthropic's AI assistant)
Claude is a large language model developed by Anthropic. This guide was produced through a structured, multi-phase research process in which Claude:
- Searched for and reviewed primary literature (systematic reviews, RCTs, Cochrane reviews, clinical guidelines)
- Extracted data, statistics, and conclusions from identified studies
- Applied GRADE certainty ratings consistently to all evidence claims
- Attempted verification of sources via Playwright browser automation (see verification status below)
- Synthesized findings into structured content without editorializing or advocating for a position
AI authorship does not reduce the obligation to cite primary sources, acknowledge uncertainty, or present evidence accurately. It is disclosed here because transparency about the authorship process is a core principle of this site — and because readers have a right to know how the content they are evaluating was produced.
Conflicts of interest
None. This site has no financial relationship with:
- Any acupuncture practitioner, practice, or professional organization
- Any pharmaceutical company or medical device manufacturer
- Any insurance company, hospital system, or healthcare provider
No advertising is displayed. No affiliate links are used. No products are recommended or sold. No sponsored content of any kind appears on this site.
Research process
Research was conducted in five phases:
- Evidence base (Phase 1): Systematic reviews and meta-analyses; mechanisms of action; institutional positions (NIH, WHO, ACP); safety profile; insurance and cost.
- Alternatives landscape (Phase 2): Conventional pain management evidence and risks; head-to-head comparisons with PT, chiropractic, and massage; biopsychosocial model of chronic pain; overprescription data.
- Presentation and trust (Phase 3): How health consumers evaluate information online; content structure patterns; language and framing; evidence visualization best practices.
- Practical guidance (Phase 4): Practitioner credentials, red flags, and selection guide; patient outcome expectations.
- Synthesis (Phase 5): Integration of all research into site architecture, evidence rating system, comparison tables, practitioner checklist, and cost/insurance reference.
Source selection criteria
Sources were selected and prioritized in this order:
- Cochrane systematic reviews (highest methodological standard)
- Individual patient data meta-analyses (e.g., Vickers 2018)
- High-quality systematic reviews and meta-analyses from peer-reviewed journals
- Large, well-designed randomized controlled trials
- Clinical practice guidelines from major national bodies (ACP, WHO, NIH/NCCIH)
- Government coverage and regulatory documents (CMS, VA)
Sources were excluded if they: came from predatory journals or journals with documented peer-review problems; extrapolated from animal models without human trial replication; consisted of testimonials or practitioner case series without control conditions.
Source verification — multi-level process
Citation audit completed — March 7, 2026
A full Playwright browser verification sweep was conducted after initial publication. 11 of 17 cited URLs contained errors: wrong PubMed IDs pointing to unrelated papers, an incorrect WHO ISBN, a broken CDC URL, a wrong Cochrane review DOI, and a CMS URL pointing to an unrelated cancer genomics document rather than the intended acupuncture NCD.
All errors were corrected on March 7, 2026. The affected citations in the source list below are marked "corrected (audit 2026-03-07)." Every factual claim supported by those sources has been cross-checked and remains accurate — only the link identifiers (PMIDs, ISBNs, DOIs, URLs) were wrong, not the paper references or extracted data.
Three-level verification protocol (applied to this audit)
- Live URL check: Each cited URL navigated via Playwright browser automation. HTTP status, page title, and visible content recorded. Cloudflare-blocked pages noted.
- Content match: Page title and author/journal confirmed against citation metadata. A URL that loads is not verified until the content matches. This step caught the CMS URL error (loaded but showed wrong document) and multiple PubMed ID transpositions.
- Cross-reference: PubMed IDs verified against DOI, journal, volume, and page range. ISBNs verified against WHO catalog. DOIs verified against Cochrane database.
Residual caveat
Two Cochrane Library URLs (Hayden CD000335 and Mu CD013814) could not be directly verified due to Cloudflare bot-blocking of automated browsers. Both were confirmed via PubMed PMID cross-check. NCCAOM.org similarly blocked automated verification; the domain is live for human visitors. All other sources were fully verified at three levels.
Evidence display standards
- GRADE certainty language is used verbatim: "results in / likely results in / may result in / very uncertain" — not paraphrased
- Evidence grades are assigned per outcome and per comparison — never at the therapy level ("acupuncture works" is not a GRADE-compatible claim)
- Natural frequencies are used as the primary format for quantitative claims ("5 out of 100 people," not "5%")
- Absolute risk is always the primary figure; relative risk is not used without accompanying absolute figures
- Uncertainty is explicitly acknowledged when present — "we don't know" is a valid and important finding
HONcode-aligned principles
HONcode (Health On the Net Foundation) was the leading health website certification standard. It was discontinued in December 2022. The principles it established remain the field standard and are implemented on this site:
- Authorship and editorial process disclosed
- Complementary to, not a replacement for, medical consultation
- Sources and dates cited for all medical claims
- Funding and conflict of interest disclosed (see above)
- Contact information available
- Advertising clearly separated from editorial content (no advertising exists on this site)
- Privacy policy (no user data is collected by this site)
Review and update policy
Last reviewed: March 7, 2026
Content should be reviewed for accuracy when significant new systematic reviews, Cochrane reviews, or major clinical guidelines are published — typically annually for active research areas. The ACP 2017 guideline is flagged throughout as potentially outdated and should be updated if ACP publishes a revision.
The missing Cochrane review for neck pain (withdrawn 2016, not replaced as of March 2026) should be updated when Cochrane publishes a replacement.
Research files
The complete research corpus — 15 structured research files covering all evidence areas — is maintained in the project repository. Each file includes raw notes, source tables, Playwright verification status, and synthesis notes. These files are not published on the site but are available on request.
Key sources cited across this site
All sources link to PubMed, Cochrane Library, or the original institutional publication. Verification status: directly accessed via browser (verified) or confirmed via abstract/search result (unverified). See caveat above.
