Disability also improved at both follow-ups (immediate: SMD = -0.49, 95% CI -0.68 to -0.30 and intermediate: SMD = -0.79, 95% CI -1.18 to -0.41). Sensitivity analyses confirmed effect robustness, especially in electroacupuncture subgroups. Certainty of evidence ranged from low to very low due to risk of bias, inconsistency, and suspected publication bias.</p><p><strong>Discussion: </strong>Acupuncture appears more effective than usual care for reducing pain and disability in adults with CLBP, but the certainty of evidence is low, warranting cautious interpretation.</p>","PeriodicalId":46378,"journal":{"name":"SICOT-J","volume":"12 ","pages":"7"},"PeriodicalIF":2.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12867475/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146114583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
