Supplementary materials for <b>Acupuncture recommendations for migraine in headache treatment guidelines: a systematic review</b>

To evaluate the quality of global headache guidelines regarding the recommendation of acupuncture for migraine treatment. We conducted a comprehensive search across 31 electronic databases and 15 guideline repositories from inception to October 2024, without language restrictions. We identified 25 guidelines meeting our inclusion criteria, and evaluated these for methodological, reporting and recommendation quality using the Appraisal of Guidelines Research and Evaluation (AGREE) II instrument, Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist and AGREE Recommendations Excellence (REX) tool, respectively. We present our findings using descriptive statistics, and assess inter-rater reliability using intraclass correlation coefficients.The detailed search strategy is included in File 1. And File 2 shows the detailed recommendations on acupuncture sessions and courses of the included guidelines (4/25).
