Conducting systematic reviews ("reviews") requires a great deal of effort and resources. Making data extracted during reviews available publicly could offer many benefits, including reducing unnecessary duplication of effort, standardizing data, supporting analyses to address secondary research questions, and facilitating methodologic research. Funded by the US Agency for Healthcare Research and Quality (AHRQ), the Systematic Review Data Repository (SRDR) is a free, web-based, open-source, data management and archival platform for reviews. Our specific objectives in this paper are to describe (1) the current extent of usage of SRDR and (2) the characteristics of all projects with publicly available data on the SRDR website.
We examined all projects with data made publicly available through SRDR as of November 12, 2019. We extracted information about the characteristics of these projects. Two investigators extracted and verified the data.
SRDR has had 2552 individual user accounts belonging to users from 80 countries. Since SRDR's launch in 2012, data have been made available publicly for 152 of the 735 projects in SRDR (21%), at a rate of 24.5 projects per year, on average. Most projects are in clinical fields (144/152 projects; 95%); most have evaluated interventions (therapeutic or preventive) (109/152; 72%). The most frequent health areas addressed are mental and behavioral disorders (31/152; 20%) and diseases of the eye and ocular adnexa (23/152; 15%). Two-thirds of the projects (104/152; 67%) were funded by AHRQ, and one-sixth (23/152; 15%) are Cochrane reviews. The 152 projects each address a median of 3 research questions (IQR 1-5) and include a median of 70 studies (IQR 20-130).
Until we arrive at a future in which the systematic review and broader research communities are comfortable with the accuracy of automated data extraction, re-use of data extracted by humans has the potential to help reduce redundancy and costs. The 152 projects with publicly available data through SRDR, and the more than 15,000 studies therein, are freely available to researchers and the general public who might be working on similar reviews or updates of reviews or who want access to the data for decision-making, meta-research, or other purposes.
进行系统评价（“综述”）需要大量的努力和资源。公开提取综述过程中所获得的数据可能会带来许多好处，包括减少不必要的重复工作、标准化数据、支持分析以解决次要研究问题，以及促进方法学研究。由美国医疗保健研究与质量局（AHRQ）资助的系统评价数据存储库（SRDR）是一个免费的、基于网络的、开源的数据管理和存储平台，适用于综述。我们在本文中的具体目标是描述（1）SRDR 的当前使用程度，以及（2）SRDR 网站上具有公开可用数据的所有项目的特征。
我们检查了截至 2019 年 11 月 12 日通过 SRDR 公开提供数据的所有项目。我们提取了这些项目特征的信息。两名调查员提取并验证了数据。
SRDR 拥有来自 80 个国家的 2552 个用户的个人账户。自 2012 年 SRDR 推出以来，已有 152 个（21%）SRDR 中的项目的数据被公开提供，平均每年 24.5 个项目。大多数项目都在临床领域（144/152 个项目；95%），大多数项目评估了干预措施（治疗或预防）（109/152；72%）。涉及的最常见健康领域是精神和行为障碍（31/152；20%）和眼部及眼附属器疾病（23/152；15%）。三分之二的项目（104/152；67%）由 AHRQ 资助，六分之一（23/152；15%）是 Cochrane 综述。这 152 个项目每个项目都解决了中位数为 3 个研究问题（IQR 1-5），并包含中位数为 70 项研究（IQR 20-130）。
在我们进入系统评价和更广泛的研究界对自动化数据提取的准确性感到满意的未来之前，由人类提取的数据的再利用有可能有助于减少冗余和成本。通过 SRDR 公开提供数据的 152 个项目，以及其中的 15000 多项研究，可供从事类似综述或综述更新的研究人员和公众免费使用，他们可能需要访问这些数据以进行决策、元研究或其他目的。
