Numerous Cochrane Reviews (CRs) in the field of physiotherapy have been published, but their conclusiveness has not been investigated. The purpose of this study was to provide an overview and describe the conclusiveness of evidence from CRs regarding physiotherapy. We conducted a systematic search using the Cochrane Database of Systematic Reviews in the Cochrane Library from 2008 through 2017 in the field of physiotherapy, the Physical Rehabilitation Evidence Database, and the CRs list on the Cochrane Rehabilitation website. Reviewers extracted the following data: year of publication, editorial group, number of articles meeting the criteria, number of patients enrolled, conclusiveness, and need for additional studies. Linear regression was used to determine whether the percentage of conclusive reviews was affected by the year of publication. Reviewers found 283 CRs in the field of physiotherapy, and only 16 (5.7%) of which were conclusive. The number of trials and participants enrolled in conclusive reviews were significantly higher than those in inconclusive reviews (P < 0.001). The percentage of conclusive reviews was significantly correlated with year of publication (P = 0.03). Almost all reviews recognized the need for additional studies. Most CRs in physiotherapy are inconclusive, and most emphasize the need for further research. The ability of a Cochrane Review to reach a conclusion is affected by the cumulative patient sample size and number of trials included in the analysis.
物理治疗领域已发表了大量Cochrane系统评价（CRs），但其结论性尚未得到研究。本研究的目的是提供一个概述，并描述来自CRs的关于物理治疗证据的结论性。我们在Cochrane图书馆的Cochrane系统评价数据库中进行了系统检索，检索时间范围为2008年至2017年，检索领域为物理治疗、物理康复证据数据库以及Cochrane康复网站上的CRs列表。评审人员提取了以下数据：发表年份、编辑组、符合标准的文章数量、纳入的患者数量、结论性以及是否需要进一步研究。采用线性回归分析来确定结论性综述的百分比是否受发表年份的影响。评审人员在物理治疗领域共找到283篇CRs，其中只有16篇（5.7%）是结论性的。结论性综述中纳入的试验数量和参与者数量显著高于非结论性综述（P<0.001）。结论性综述的百分比与发表年份显著相关（P = 0.03）。几乎所有综述都认识到需要进一步研究。物理治疗领域的大多数CRs都没有得出结论，且大多数都强调需要进一步研究。Cochrane系统评价得出结论的能力受分析中累积患者样本量和纳入试验数量的影响。
