Publication bias has been recognized as a problem in ecology and evolution that can undermine reviews of research results. Unfortunately, direct tests of publication bias are extremely rare. Here, we quantify a well-discussed but, to our knowledge, previously untested form of publication bias: the publication of results with and without estimates of effect size. We find that results published without effect sizes are a biased sample of those that are published. This further complicates the already difficult task of compiling quantitative literature reviews and meta-analytic studies.
发表偏倚已被公认为生态学和进化领域中的一个问题，它可能会破坏对研究结果的综述。不幸的是，对发表偏倚的直接检验极为罕见。在此，我们对一种虽被广泛讨论但据我们所知此前未经验证的发表偏倚形式进行了量化：即有和没有效应量估计的结果的发表情况。我们发现，未报告效应量而发表的结果是已发表结果中的一个有偏样本。这使得编制定量文献综述和荟萃分析研究这一原本就困难的任务变得更加复杂。
