Scholarly output has typically been measured by citation-based metrics such as the Hirsch index (h-index). The Altmetric Attention Score has emerged as a substitute to measure digital attention given to a project. This study aims to determine whether there is any correlation between h-index and the Altmetric score in the plastic surgery literature.
Article metrics (full-text views, abstract views, PDF downloads, times e-mailed, Altmetric Attention Score, times tweeted, and number of citations by posts) were extracted from articles published in Plastic and Reconstructive Surgery over a 2-year period. Author metrics, including h5-index, were also collected. Pairwise correlations were performed using Spearman's rank correlation coefficient (r).
A total of 1668 articles were published, with 971 included. Altmetric Attention Scores showed strong correlation with other article metrics (r = 0.48 to 0.97; p < 0.001) but weak correlation with h5-index (r = 0.14; p < 0.001) and sum of times cited without self-citation (r = 0.14; p < 0.001). It did not correlate with total publications, average citations per item, or sum of times cited. The h5-indexes showed strong positive correlation with other author bibliometrics (r = 0.66 to 0.97; p < 0.001); moderate correlation with times e-mailed (r = 0.41; p < 0.001); weak correlation with number of citations by posts (r = 0.10; p = 0.002); and no correlation with full-text views, abstract views, PDF downloads, and times tweeted.
The Altmetric Attention Score and conventional senior author bibliometrics have weak positive correlation at best and appear to have distinct but complementary roles in measuring scholarly output.
学术产出通常通过引文计量指标来衡量，如 Hirsch 指数（h-index）。Altmetric 关注度分数已作为衡量项目数字关注度的替代指标出现。本研究旨在确定在整形外科学文献中，h-index 与 Altmetric 分数之间是否存在相关性。
从《整形与重建外科》杂志上发表的文章中提取了 2 年内的文章指标（全文浏览量、摘要浏览量、PDF 下载量、电子邮件发送次数、Altmetric 关注度分数、推文次数和文章被引次数）。还收集了作者指标，包括 h5-index。使用 Spearman 秩相关系数（r）进行了两两相关性分析。
共发表了 1668 篇文章，其中有 971 篇被纳入分析。Altmetric 关注度分数与其他文章指标高度相关（r = 0.48 至 0.97；p < 0.001），但与 h5-index（r = 0.14；p < 0.001）和不包括自引的被引次数总和（r = 0.14；p < 0.001）相关性较弱。它与总出版物数量、每篇文章的平均被引次数或被引次数总和均无相关性。h5-index 与其他作者计量学指标高度相关（r = 0.66 至 0.97；p < 0.001）；与电子邮件发送次数中度相关（r = 0.41；p < 0.001）；与帖子被引次数弱相关（r = 0.10；p = 0.002）；与全文浏览量、摘要浏览量、PDF 下载量和推文次数无相关性。
Altmetric 关注度分数和传统的资深作者计量学指标最多只有微弱的正相关性，它们在衡量学术产出方面似乎具有不同但互补的作用。
