Alternative metrics are emerging scores to assess the impact of research beyond the academic environment.
To analyse whether a correlation exists between manuscript characteristics and alternative citation metrics.
This bibliometric analysis included original articles published in the five journals with the highest impact factors during 2019. We extracted the following characteristics from each record: journal, publication month, title, number of authors, type of institution, type of publication, research topic, number of references, financial support, free/open access status and literature citations. The main measure was the identification of variables of higher social attention (measured by the Altmetric Attention Score ≥25) using binary logistic regression. Model performance was assessed by the change in the area under the curve (AUC).
A total of 840 manuscripts were included. The Altmetric scores across all five journals ranged from 0 to 465 (mean 12.51 ± 33.7; median 3). The most prevalent topic was skin cancer, and the study design was clinical science. The scientific journal (P < 0.001), the presence of conflicts of interest (OR 2.2 [95%CI 1.3-3.7]; P = 0.002) and open access status OR 3.2 [95%CI 1.6-6.7]; P = 0.002) were found as independent predictors of high Altmetric scores.
Our study suggests an article´s social recognition may be dependent on some manuscript characteristics, thus providing useful information on the dissemination of dermatology research to the general public.
替代计量指标是评估学术环境之外研究影响力的新兴指标。
分析手稿特征与替代引文指标之间是否存在相关性。
本文献计量学分析包括在 2019 年影响因子最高的五本期刊上发表的原始文章。我们从每条记录中提取以下特征:期刊、出版月份、标题、作者数量、机构类型、出版物类型、研究主题、参考文献数量、财务支持、是否开放获取以及文献引用。主要措施是使用二元逻辑回归识别具有较高社会关注度的变量(通过 Altmetric 关注度得分≥25 进行衡量)。通过曲线下面积(AUC)的变化来评估模型性能。
共纳入 840 篇手稿。所有五本期刊的 Altmetric 分数范围从 0 到 465(平均值 12.51±33.7;中位数 3)。最常见的主题是皮肤癌,研究设计是临床科学。科学期刊(P<0.001)、存在利益冲突(OR 2.2[95%CI 1.3-3.7];P=0.002)和开放获取状态(OR 3.2[95%CI 1.6-6.7];P=0.002)被发现是高 Altmetric 分数的独立预测因素。
我们的研究表明,文章的社会认可度可能取决于一些手稿特征,从而为向公众传播皮肤病学研究提供了有用的信息。
