OBJECTIVE
The researchers assessed prevalence in the clinical case report literature of multiple reports independently reporting the same (or nearly the same) main finding.
METHODS
Results from forty-five PubMed queries were examined for incidence and features of main findings ("nuggets") shared in at least four case reports.
RESULTS
The authors found that nuggets are surprisingly prevalent and large in the case report literature, the largest found so far was reported in seventeen articles. In most cases, the main findings of case reports were evident from examining titles alone.
CONCLUSIONS
Our curated examples should serve as gold standards for developing specific automated methods for finding nuggets. Nuggets potentially enable finding-based (instead of topic-based) information retrieval.
目的
研究人员评估了临床病例报告文献中多个报告独立报告相同（或几乎相同）主要发现的发生率。
方法
检查了45个PubMed检索结果，以了解至少4篇病例报告中共享的主要发现（“要点”）的发生率和特征。
结果
作者发现，要点在病例报告文献中惊人地普遍且数量众多，目前发现的最大数量在17篇文章中被报道。在大多数情况下，仅通过查看标题就能明显看出病例报告的主要发现。
结论
我们精心挑选的例子应作为开发用于查找要点的特定自动化方法的黄金标准。要点可能实现基于发现（而非基于主题）的信息检索。
