This article addresses different ways to identify knowledge gaps in placebo research. Following a short description of the history of placebo research and our contributions, we describe the creation of the Journal of Interdisciplinary Placebo Studies (JIPS) literature database and compare its content (on a meta-level) with two other approaches to survey the current state of the art of placebo research: a bibliometric analysis of a (limited) selection of placebo papers, and the analysis of the content of all abstracts submitted to a 2017 placebo conference. We summarize this discussion with a critical assessment of these approaches and a perspective of future approaches in such placebo "meta"-analyses.
本文探讨了识别安慰剂研究中知识空白的不同方法。在简要描述安慰剂研究的历史和我们的贡献之后，我们描述了创建《跨学科安慰剂研究杂志》（JIPS）文献数据库的过程，并将其内容（在元水平上）与另外两种调查安慰剂研究现状的方法进行了比较：对（有限的）一组安慰剂论文进行文献计量分析，以及对提交给 2017 年安慰剂会议的所有摘要内容进行分析。我们通过对这些方法的批判性评估和对未来此类安慰剂“元分析”方法的展望，对这一讨论进行了总结。
