发表偏倚是指研究者、审稿人和编辑根据研究结果的方向或强度提交或接受稿件以供发表的倾向。关于发表偏见的大部分知识来自社会科学，而不是医学领域。在医学上，有三项研究为这种偏见提供了直接证据。无论从科学角度（知识的全面传播）还是从联合收割机从一些类似研究（荟萃分析）的结果的角度来看，防止发表偏倚都很重要。如果治疗决策是基于已发表的文献，则文献必须包括所有质量可接受的可用数据。目前，很难甚至不可能获得某一领域所有研究的信息。临床试验的注册，也许还有其他类型的研究，是科学界应该前进的方向。
Publication bias is the tendency on the parts of investigators, reviewers, and editors to submit or accept manuscripts for publication based on the direction or strength of the study findings. Much of what has been learned about publication bias comes from the social sciences, less from the field of medicine. In medicine, three studies have provided direct evidence for this bias. Prevention of publication bias is important both from the scientific perspective (complete dissemination of knowledge) and from the perspective of those who combine results from a number of similar studies (meta-analysis). If treatment decisions are based on the published literature, then the literature must include all available data that is of acceptable quality. Currently, obtaining information regarding all studies undertaken in a given field is difficult, even impossible. Registration of clinical trials, and perhaps other types of studies, is the direction in which the scientific community should move.
