The number of citations of a scientific article is considered a weight of that work in the field of interest. Bibliometric analysis of the most cited articles conducted in some medical disciplines has identified the most relevant scientific contributions that pushed forward knowledge and clinical practice of that discipline.
We conducted a bibliometric analysis of the most cited articles in nephrology, by extracting relevant words that identify issues of nephrological interest and querying the Google Scholar database. A rank with the 100 most cited articles was obtained, based on the absolute number of citations. Articles were clustered in different areas of interest.
Word(s) extracted from the Google Scholar database that restituted at least 100 000 hits were 50. The extracted 100 most cited articles collected cumulatively >285 000 citations. Nine subcategories were identified and the most populated one was 'Renal function assessment' (16 articles and 68 000 citations, 24% of total). The other relevant group of articles (16, with 46 652 citations) belonged to the category 'Randomized trials and pharmacology'. Almost 70% of the articles in the top 100 were published by eight major international journals. The top 100 list included 62 articles generated from USA scientists and the author with higher number of articles was A.S. Levey (10).
The top 100 list of articles in nephrology helps delineate the major interests of this medical discipline. Assessment of renal functions, probably for its multidisciplinary relevance, is the heaviest topic, based on number of citations.
一篇科学文章的被引次数被视为该著作在相关领域的影响力。对某些医学学科中被引次数最多的文章进行文献计量分析，可确定推动该学科知识和临床实践发展的最相关科学贡献。
我们通过提取能识别肾脏病相关问题的关键词，并查询谷歌学术数据库，对肾脏病领域被引次数最多的文章进行了文献计量分析。根据被引次数的绝对值，获得了被引次数最多的100篇文章的排名。文章被归类到不同的感兴趣领域。
从谷歌学术数据库中提取的能返回至少100000条结果的关键词有50个。提取的100篇被引次数最多的文章累计被引超过285000次。确定了9个亚类，其中数量最多的是“肾功能评估”（16篇文章，68000次引用，占总数的24%）。另一组相关文章（16篇，46652次引用）属于“随机试验与药理学”类别。前100篇文章中近70%由8种主要国际期刊发表。前100名榜单中有62篇文章由美国科学家撰写，文章数量最多的作者是A.S. Levey（10篇）。
肾脏病领域被引次数最多的100篇文章榜单有助于勾勒出该医学学科的主要研究兴趣。基于被引次数，肾功能评估可能因其多学科相关性，是最重要的主题。
