背景系统评价用于评估和总结研究，因此有助于公共卫生和健康促进政策和实践的决策。系统评价结果的有效性在很大程度上取决于所使用的数据收集方法。1这包括系统搜索以找到所有相关研究，这通常是一项困难和具有挑战性的任务。已经进行了大量的公共卫生和健康促进研究，但只有一部分是在公共领域，总的来说，文献是广泛分散的。2本文旨在强调围绕发表偏倚的一些问题，包括数据库偏倚、语言偏倚和灰色文献偏倚，并在可用的情况下用公共卫生实例说明这些问题。发表偏倚是指根据研究结果的性质和方向而决定是否发表研究结果。3-6方法，以防止或最大限度地减少出版物的偏见，包括概述的作用，科克伦健康促进和公共卫生领域（HP&PH领域），以改善获得“难以定位”的健康促进和公共卫生干预研究和有效性审查。
BackgroundSystematic reviews are used to assess and summarize research, and therefore are instrumental to decision-making in public health and health promotion policy and practice. The validity of the results of a systematic review is highly dependent on the data collection methods used. 1 This includes a systematic search to locate all relevant studies, which is often a difficult and challenging task. A great deal of public health and health promotion research has been conducted, but only some of it is available in the public domain, and overall the literature is widely dispersed. 2 This paper aims to highlight some of the issues surrounding publication bias, including database bias, language bias and grey literature bias, and to illustrate these issues with public health examples where available. Publication bias is defined here as the publication or non-publication of research findings based on the nature and direction of results. 3-6 Methodology to prevent or minimize publication bias is described, including an outline of the role of the Cochrane Health Promotion and Public Health Field (the HP&PH Field) in improving access to'difficult to locate'health promotion and public health intervention studies and effectiveness reviews.
