Acupuncture for Cancer-related Insomnia

The following databases were searched, starting from inception to June 7, 2022: PubMed, Embase, Web of Science, The Cochrane Library, Wan Fang database, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), and the China Science and Technology Journal Database (VIP). The inclusion criteria and search strategy were established according to the PRISMA protocol guidelines (15 (link)). The following three sets of search terms were adopted in English: (neoplasms OR cancer OR tutor OR malignancy) AND (sleep initiation and maintenance disorders OR insomnia OR early awakening OR disorders of initiating and maintaining sleep) AND (acupuncture therapy OR acupuncture OR moxibustion). All searches were limited to human randomized controlled trials (RCTs) and conducted independently by two authors in an electronic database. Relevant Chinese search terms were also searched. To obtain possible related experiments, the references of the original articles and review articles were searched manually. Meanwhile, a combination of subject and free words were used as the search words. The PubMed search strategy is presented in Supplementary Table S1, and appropriate adjustments to this strategy were made for other databases.
