1 Introduction

Editors of a number of OBGYN journals have formed an OBGYN Editors' Integrity Group (OGEIG), with the aim of collaborating to improve trustworthiness in published papers.¹ These Editors have already jointly agreed and published quality criteria for randomized controlled trials (RCTs), incorporating the guidance in their instructions to authors.² The requirements for RCTs include:

• prospective registration in an international clinical trials registry platform, with registration number provided;
• statement of ethical approval, with name of approving committee;
• statement of informed consent;
• statement of adherence to CONSORT guidelines (and, ideally, provision of a CONSORT checklist to be published as supplementary material);
• and a data-sharing statement.²

Meta-analysis is a quantitative statistical technique used to combine and analyze data from the results of multiple previous independent studies on a particular topic, to derive overall conclusions or effect estimates. In general (but not exclusively), meta-analyses are based on RCTs. The results are often used to develop standard practice or clinical guidelines. However, RCTs may be inaccurate or fabricated, leading to journal withdrawal or retraction. This article aims to expand upon the list of RCT quality criteria for authors of meta-analyses of RCTs, so that low-quality and fabricated studies are excluded from meta-analyses.

随机对照研究荟萃分析的可信度标准：OBGYN 期刊指南

 1 引言

许多 OBGYN 期刊的编辑成立了 OBGYN 编辑诚信小组 （OGEIG），旨在合作提高已发表论文的可信度。¹ 这些编辑已经共同商定并发布了随机对照试验 （RCT） 的质量标准，并将该指南纳入他们给作者的说明中。² RCT 的要求包括：

• 
  在国际临床试验注册平台进行前瞻性注册，并提供注册号;
• 
  伦理批准声明，并附有批准委员会的名称;
• 
  知情同意声明;
• 
  遵守 CONSORT 指南的声明（理想情况下，提供 CONSORT 清单作为补充材料发布）;
• 
  以及数据共享声明。^{阿拉伯数字}

荟萃分析是一种定量统计技术，用于组合和分析来自特定主题的多个先前独立研究结果的数据，以得出总体结论或效果估计。一般来说（但不限于），meta分析是基于RCTs的。结果通常用于制定标准实践或临床指南。然而，RCT 可能不准确或捏造，导致期刊撤回或撤稿。本文旨在扩展 RCT 荟萃分析作者的 RCT 质量标准列表，以便将低质量和捏造的研究排除在荟萃分析之外。
