This study aims to assess the use, impact, and dissemination of preprints in dentistry.
This is a meta-research study with a cross-sectional design. We included preprints published in dentistry, regardless of the year of publication. Searches were performed in the medRxiv.org and Preprints.org platforms and restricted to English. One researcher extracted the data, and another researcher verified data consistency. The following data were extracted: year of publication, country of the corresponding author, number of abstract and full-text views and downloads, Altmetric attention score, whether the preprint was mentioned in other servers such as Twitter and Publons, number of mentions in other servers, number of citations in the Dimensions database, and whether the preprint had already been published in a peer-reviewed journal. If already published, we extracted the journal's impact factor (JCR 2021) and the number of citations in the Dimensions database. We conducted a descriptive analysis of the extracted characteristics and explored relationships between metrics using the Spearman correlation.
We identified 276 preprints. Most of the studies were published between 2020 and 2022 (n = 229), especially those from ten countries. The most-cited preprint and published article are the same study. Only the correlation between the number of preprint citations and peer-reviewed article citations in the Dimensions database showed a large positive association (Spearman's rho = 0.5809).
Preprints gained popularity over the last several years due to the COVID-19 pandemic and reached a larger audience, especially on platforms such as Twitter.
Preprint publishing allows faster dissemination of science for the benefit of society.
本研究旨在评估预印本在牙科学中的使用、影响和传播。
这是一项具有横断面设计的元研究。我们纳入了发表在牙科学中的预印本，无论出版年份如何。在 medRxiv.org 和 Preprints.org 平台上进行了检索，并仅限于英文。一名研究人员提取数据，另一名研究人员验证数据一致性。提取的数据包括：出版年份、通讯作者所在国家/地区、摘要和全文浏览量和下载量、Altmetric 关注度评分、预印本是否在其他服务器（如 Twitter 和 Publons）上被提及、在其他服务器上的提及次数、Dimensions 数据库中的引用次数以及预印本是否已在同行评议期刊上发表。如果已发表，我们提取了期刊的影响因子（JCR 2021）和 Dimensions 数据库中的引用次数。我们对提取的特征进行了描述性分析，并使用 Spearman 相关分析探索了指标之间的关系。
我们确定了 276 篇预印本。大多数研究发表于 2020 年至 2022 年之间（n=229），尤其是来自十个国家的研究。被引用最多的预印本和已发表的文章是同一研究。只有预印本在 Dimensions 数据库中的引用次数与同行评议文章引用次数之间的相关性显示出较大的正相关（Spearman 的 rho=0.5809）。
由于 COVID-19 大流行，预印本在过去几年中变得流行起来，受众群体更广，尤其是在 Twitter 等平台上。
预印本的发表允许更快地传播科学，造福社会。
