| Checklists |
• AMSTAR 2 |
| Aim | To assess the methodological quality (AMSTAR 2) and overall confidence in the results of systematic reviews of exercise therapy for chronic non-specific low back pain published up to February 2017. |
| Level of Investigation | Descriptive |
| Summary of Findings | 21% of 38 included systematic reviews had a protocol published or registered prospectively. The overall confidence in the results of 74% of included reviews was rated using AMSTAR 2 as ‘Critically low’; 16% as ‘Low’, 2% as Moderate, and 8% were rated as ‘High’. Reviews performed most poorly with respect to: explaining selection of the study designs (8%); reporting sources of funding for included studies (11%); assessing potential impact of risk of bias in individual studies on the results of the meta-analyses (13%); investigation of publication bias (21%); and establishing review methods prior to conduct of the review (21%). |
