Data_Sheet_2_Efficacy and safety of yoga for the management of chronic low back pain: an overview of systematic reviews.docx

BackgroundYoga is a non-pharmacological conservative therapeutic modality that can be employed for the management of chronic low back pain (CLBP). In this overview, we have summarized and evaluated data from current systematic reviews (SRs) on the use of yoga for CLBP.
MethodsWe comprehensively searched SRs on the use of yoga for CLBP in nine electronic databases from inception to September 2023. The methodological quality was evaluated using the Assessment of Multiple Systematic Review Scale-2 (AMSTAR-2). The reporting quality of the included SRs was evaluated using the Preferred Reporting Item for Systematic Review and Meta-Analysis-2020 (PRISMA-2020), and the quality of data was graded using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Two independent researchers performed the screening, data extraction, and quality assessment process of SRs.
ResultsA total of 13 SRs were included. The results of the AMSTAR-2 indicated that the methodological quality of the included studies was relatively low. The PRISMA-2020 checklist evaluation results indicated that methodological limitations in reporting, especially regarding data processing and presentation, were the main weaknesses. The GRADE assessment indicated that 30 outcomes were rated moderate, 42 were rated low level, and 20 were rated very low level. Downgrading factors were mainly due to the limitations of the included studies.
ConclusionYoga appears to be an effective and safe non-pharmacological therapeutic modality for the Management of CLBP. Currently, it may exhibit better efficacy in improving pain and functional disability associated with CLBP. However, the methodological quality and quality of evidence for SRs/MAs in the included studies were generally low, and these results should be interpreted cautiously.

背景 瑜伽是一种非药物保守治疗手段，可用于慢性腰痛（chronic low back pain, CLBP）的管理。本概述对当前针对瑜伽用于CLBP治疗的系统评价（systematic reviews, SRs）相关数据进行了总结与评估。
方法 本研究全面检索了9个电子数据库自建库至2023年9月期间收录的、关于瑜伽用于CLBP治疗的SRs。采用多系统评价评价量表-2（AMSTAR-2）评估纳入SRs的方法学质量；采用《系统评价与Meta分析优先报告条目2020》（PRISMA-2020）评价纳入SRs的报告质量；采用推荐分级的评估、制定与评价系统（GRADE）对数据质量进行分级。由2名独立研究者分别完成SRs的筛选、数据提取及质量评估流程。
结果 最终共纳入13项SRs。AMSTAR-2评估结果显示，纳入研究的方法学质量普遍偏低。PRISMA-2020清单评估结果表明，报告环节存在方法学局限，尤以数据处理与呈现方面的缺陷最为突出，为主要短板。GRADE评估显示，30项结局指标被评为中等质量，42项为低质量，20项为极低质量；证据降级的主要原因在于纳入研究本身存在局限性。
结论 瑜伽作为一种非药物治疗手段，用于CLBP的管理兼具有效性与安全性。现有研究显示，瑜伽在改善CLBP相关疼痛及功能残疾方面可取得更优疗效。但纳入研究中系统评价/Meta分析（SRs/MAs）的方法学质量与证据质量整体偏低，因此对本研究结果应谨慎解读。
