Nearly 40 y have passed since the 1983 National Institutes of Health Consensus-Development-Conference, which has turned liver transplantation (LT) from a clinical experiment into a routine therapeutic modality. Since' clinical LT has changed substantially. We aimed to comprehensively analyze the publication trends in the most-cited top-notch literature in LT science over a 4-decade period.
A total of 106 523 items were identified between January 1981 and May 2021 from the Web of Science Core Collection. The top 100 articles published were selected using 2 distinct citation-based strategies to minimize bias. Various bibliometric tools were used for data synthesis and visualization.
The citation count for the final dataset of the top 100 articles ranged from 251 to 4721. Most articles were published by US authors (n = 61). The most prolific institution was the University of Pittsburgh (n = 15). The highest number of articles was published in Annals of Surgery, Hepatology, and Transplantation ; however, Hepatology publications resulted in the highest cumulative citation of 9668. Only 10% of the articles were classified as evidence level 1. Over 90% of first/last authors were male. Our data depict the evolution of research focus over 40 y. In part, a disproportional flow of citations was observed toward already well-cited articles. This might also project a slowed canonical progress, which was described in other fields of science.
This study highlights key trends based on a large dataset of the most-cited articles over a 4-decade period. The present analysis not only provides an important cross-sectional and forward-looking guidance to clinicians, funding bodies, and researchers but also draws attention to important socio-academic or demographic aspects in LT.
自 1983 年美国国立卫生研究院共识发展会议以来，近 40 年过去了，该会议将肝移植（LT）从临床实验转变为常规治疗方式。自临床 LT 以来，发生了重大变化。我们旨在全面分析过去 40 年中 LT 科学领域最具影响力的顶级文献的发表趋势。
我们从 Web of Science 核心合集数据库中确定了 1981 年 1 月至 2021 年 5 月期间共 106523 项研究。使用 2 种不同的基于引文的策略选择前 100 篇文章，以尽量减少偏差。使用各种文献计量工具进行数据综合和可视化。
最终数据集的前 100 篇文章的引文数从 251 到 4721 不等。大多数文章的作者来自美国（n = 61）。最具影响力的机构是匹兹堡大学（n = 15）。发表文章数量最多的期刊是《外科学年鉴》、《肝脏病学》和《移植学》，但《肝脏病学》杂志的文章获得的总引文数最高，为 9668 次。仅有 10%的文章被归类为证据水平 1。第一/最后作者中 90%以上为男性。我们的数据描绘了 40 年来研究重点的演变。部分原因是已被大量引用的文章获得了不成比例的引用。这也可能反映了其他科学领域描述的规范进展放缓。
本研究基于过去 40 年中最具影响力的文章的大数据集，强调了关键趋势。本分析不仅为临床医生、资助机构和研究人员提供了重要的横断面和前瞻性指导，还引起了人们对 LT 中的重要社会学术或人口统计学方面的关注。
