Introduction Primary dysmenorrhea (PD) is the most common gynecological condition among young women. Although several non-pharmacological interventions have proven effective in relieving pain in patients with PD, the optimal treatment remains unknown. This systematic review and network meta-analysis (NMA) will aim to compare and rank the analgesic effects of different non-drug interventions for PD. Methods and analysis Randomized controlled trials of non-pharmacological interventions for PD will be identified via a search of the PubMed, Cochrane Library, Web of Science, and Embase databases until May 2024. The primary outcome will be change in pain intensity among patients with PD, while the secondary outcomes include health-related quality of life and symptoms of depression and anxiety. Two independent reviewers will perform document screening, study selection, and data extraction. The methodological quality of the included studies will be assessed using the Cochrane Risk of Bias tool (V. 2). The RevMan, Stata, and Aggregate Data Drug Information System software will be used to perform a pairwise meta-analysis and Bayesian NMA in a random-effects model. The certainty of the evidence will be rated using the Grading of Recommendations, Assessment, Development, and Evaluation System.

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
