2011 年以来使用 hT 指数对血液透析和腹膜透析领域做出最大贡献的作者：文献计量学分析。

BACKGROUND: The h-index does not take into account the full citation list of a researcher to evaluate individual research achievements (IRAs). As a generalization of the h-index, the hT-index takes all citations into account to evaluate IRAs. Compared to other bibliometric indices, it is unclear whether the hT-index is more closely associated with the h-index. We utilized articles published on hemodialysis and peritoneal dialysis (HD/PD) to validate the hT-index as a measure of the most significant contributions to HD/PD. METHODS: Using keywords involving HD/PD in titles, subject areas, and abstracts since 2011, we obtained 7702 abstracts and their associated metadata (e.g., citations, authors, research institutes, countries of origin). In total, 4752 first or corresponding authors with hT-indices >0 were evaluated. To present the author's IRA, the following 4 visualizations were used: radar, Sankey, impact beam plot, and choropleth map to investigate whether the hT-index was more closely associated with the h-index than other indices (e.g., g-/x-indices and author impact factors), whether the United States still dominates the majority of publications concerning PD/HD, and whether there was any difference in research features between 2 prolific authors. RESULTS: In HD/PD articles, we observed that (a) the hT-index was closer to and associated with the h-index; (b1) the United States (37.15), China (34.63), and Japan (28.09) had the highest hT-index; (b2) Sun Yat Sen University (Chian) earned the highest hT-index (=20.02) among research institutes; (c1) the authors with the highest hT-indices (=15.64 and 14.39, respectively) were David W Johnson (Australia) and Andrew Davenport (UK); and (c2) their research focuses on PD and HD, respectively. CONCLUSION: The hT-index was demonstrated to be appropriate for assessing IRAs along with visualizations. The hT-index is recommended in future bibliometric analyses of IRAs as a complement to the h-index.

背景：h 指数没有考虑到研究人员的完整引文列表来评估个人研究成果（IRAs）。作为 h 指数的推广，hT 指数考虑了所有的引文来评估 IRAs。与其他文献计量指标相比，hT 指数是否与 h 指数更密切相关尚不清楚。我们利用血液透析和腹膜透析（HD/PD）相关的文章来验证 hT 指数作为评估对 HD/PD 最有意义贡献的指标。

方法：自 2011 年以来，我们使用标题、主题领域和摘要中涉及 HD/PD 的关键词，获得了 7702 篇摘要及其相关元数据（如引文、作者、研究机构、原籍国）。共有 4752 位 hT 指数>0 的第一或通讯作者进行了评估。为了展示作者的 IRA，我们使用了以下 4 种可视化方法：雷达图、Sankey 图、影响光束图和专题地图，以研究 hT 指数是否比其他指标（如 g-/x-指数和作者影响因素）更密切地与 h 指数相关，美国是否仍然主导着大多数关于 PD/HD 的出版物，以及两位高产作者之间的研究特征是否存在差异。

结果：在 HD/PD 文章中，我们观察到：（a）hT 指数与 h 指数更接近且相关；（b1）美国（37.15）、中国（34.63）和日本（28.09）的 hT 指数最高；（b2）中山大学（中国）在研究机构中获得了最高的 hT 指数（=20.02）；（c1）hT 指数最高的作者（分别为 15.64 和 14.39）为澳大利亚的 David W Johnson 和英国的 Andrew Davenport；（c2）他们的研究重点分别是 PD 和 HD。

结论：hT 指数被证明是评估个人研究成果的一种合适方法，结合可视化方法。建议在未来的个人研究成果文献计量分析中，将 hT 指数作为 h 指数的补充进行使用。
