研究目的:

向存在错误证据的系统综述的作者或编辑发送电子邮件通知是否能够加快去除这些错误证据的过程。比较同时向编辑和作者发送警报与仅向编辑或作者发送警报的效果差异,评估不同干预措施对证据修复的影响。  

Objectives of Study:

Sending an email to the authors or editors of a systematic review containing erroneous evidence to notify them may speed up the process of removing this erroneous evidence. Compare the effects of sending alerts to both editors and authors simultaneously with sending alerts to only editors or only authors, and assess the impact of different interventions on evidence correction.

纳入标准:

我们将确定符合以下所有纳入标准的合格 SR(受污染的 SR): 1.在证据综合中至少纳入一项已撤回试验的系统评价; 2.系统综述侧重于医疗保健干预措施; 3.在随机分组前,对于已撤回的试验,未采取任何纠正措施,例如修正和更新; 4.更新版本仍需综合已撤回的试验(例如,Cochrane综述)。

Inclusion criteria

We will identify eligible SRs (contaminated SRs) that meet all of the following inclusion criteria: 1.SRs that synthesize at least one retracted trial in evidence synthesis; 2.SRs focused on healthcare interventions; 3.No correction action regarding the retracted trials prior to randomization, such as correction, and updating; 4.Updated version remaining to synthesize retracted trials (e.g., Cochrane reviews).

排除标准:

如果系统总数审查符合任何排除标准,则该受污染的系统评价将被排除: 1.系统评价本身已被撤回; 2.在最新版的针对性系统评价中已删除了被撤回的试验,并且结论也已相应更新; 3.编辑将其标记为关切表达的系统评价; 4.由于这些研究存在可复现的问题,用于元回归分析和其他可复现性研究(例如,伞形综述)所使用的证据被排除; 5.发表在预印本网站(例如,medRxiv)上的系统评价; 6.以非英语语言发表的系统评价; 7.以简短报告或会议摘要形式发表的系统评价。

Exclusion criteria:

And, contaminated SRs will be excluded if reviews meet any of the exclusion criteria: 1.SRs themselves have been retracted; 2.Retracted trials having been removed in the latest version of targeted SRs and conclusion having been updated accordingly; 3.SRs labelled as an expression of concern by editors; 4.Evidence used for meta-regression analysis and other reproducibility study (e.g., umbrella reviews), due to burden of replication to these studies; 5.SRs published on pre-print websites (e.g., medRxiv); 6.SRs published in non-English languages; 7.SRs published as short reports or conference abstracts.

随机方法(请说明由何人用什么方法产生随机序列):

独立的统计学家和计算机专家将利用计算机生成的随机数为三个组生成随机化序列。

Randomization Procedure (please state who generates the random number sequence and by what method):

Randomization will be performed to allocate eligible SRs into three groups at a 1:1:1 ratio: (Group A) e-mail alert to journal editors, (Group B) e-mail alert to authors, and (Group C) control (no intervention). The independent statisticians and computer specialists will generate the randomization sequence using a computer-generated random number for three groups. The sequence will be generated for each stratum to ensure balanced allocation with impact quartiles.

盲法:

由于行为性电子邮件干预的特性,本研究将采用部分盲法设计。结果评估员与数据分析员将对分组分配情况保持盲态。

Blinding:

The study will adopt a partially blinded design due to the nature of behavioral email interventions. There are outcome assessors, and data analysts that will be blinded to group allocation.
