这项研究确定了临床肥胖研究文章产量最高的期刊，并调查了此类研究在期刊中的分布情况。该研究举例说明了一种建立期刊集的方法，该期刊集可能包含某个领域的最新知识。 40 篇有关肥胖主题的系统综述（“纳入研究”）中引用的所有原始研究均已汇编，并提取了它们发表的期刊标题。这些期刊按照纳入研究的数量进行排名。确定了临床肥胖症产量最高的期刊以及期刊标题的分布情况。这些期刊的一个子集是在 MEDLINE (PubMed) 中创建的，用于测试肥胖治疗高质量研究的搜索召回率和精确度（即通过预定方法标准的文章，包括将参与者随机分配到对照组、临床结果评估和至少 80% 的随访）。系统评价引用了 252 种期刊的文章。产量最高的三本期刊专门研究肥胖问题，但它们只发表了 19.2% 的研究成果，而 80.8% 的研究分散在 249 种非肥胖期刊中。 MEDLINE 期刊子集包含 241 种期刊（11 种期刊未在 MEDLINE 中索引），包括通过搜索高质量治疗研究检索到的 82% 的临床肥胖研究文章（“召回率”为 82%），检索到的文章中 11% 是关于临床肥胖护理的（“精确度”为 11%），而完整 MEDLINE 数据库中肥胖治疗研究的精确度为 6%。肥胖期刊仅收录了临床肥胖护理文献的一小部分。那些希望在这一领域保持领先地位的人需要制定比阅读这些专业期刊更具包容性的策略。在搜索大型电子数据库以提高搜索精度时，基于这些发现的期刊子集可能会很有用。
This study identified the journals with the highest yield of clinical obesity research articles and surveyed the scatter of such studies across journals. The study exemplifies an approach to establishing a journal collection that is likely to contain most new knowledge about a field. All original studies that were cited in 40 systematic reviews about obesity topics (“included studies”) were compiled and journal titles of where they were published were extracted. The journals were ranked by the number of included studies. The highest yielding journals for clinical obesity and the scatter across journal titles were determined. A subset of these journals was created in MEDLINE (PubMed) to test search recall and precision for high quality studies of obesity treatment (i.e., articles that pass predetermined methodology criteria, including random allocation of participants to comparison groups, assessment of clinical outcomes, and at least 80% follow-up). Articles in 252 journals were cited in the systematic reviews. The three highest yielding journals specialized in obesity but they published only 19.2% of the research, leaving 80.8% scattered across 249 non-obesity journals. The MEDLINE journal subset comprised 241 journals (11 journals were not indexed in MEDLINE) and included 82% of the clinical obesity research articles retrieved by a search for high quality treatment studies (“recall” of 82%) and 11% of the articles retrieved were about clinical obesity care (“precision” of 11%), compared with precision of 6% for obesity treatment studies in the full MEDLINE database. Obesity journals captured only a small proportion of the literature on clinical obesity care. Those wishing to keep up in this field will need to develop more inclusive strategies than reading these specialty journals. A journal subset based on these findings may be useful when searching large electronic databases to increase search precision.
