The objective of this study was to examine the correlation between Twitter mentions and the number of academic citations of radiation oncology articles.
We reviewed all 178 clinical manuscripts of the 2 most important radiation oncology journals and "Brachytherapy," and all clinical manuscripts relating to radiation oncology from the top 10 impact factor oncology journals, published between January and February 2018. We collected the record of citations utilizing Scopus and Google Scholar platforms and the number of times an article was tweeted about using the "Altmetric Bookmarklet." χ test was used to compare distributions between groups and the Pearson coefficient was used for correlations between the Twitter metrics and academic citations.
Overall, 71% of all articles were tweeted about at least once. There was a significant correlation between the number of tweets and the number of citations in Google Scholar (r=0.55, P<0.001) and in Scopus (r=0.59, P<0.001). The 11% of articles with a prepublication Twitter "buzz" (defined as an article with ≥10 tweets before publication) had 3.6 times more citations in Scopus (mean: 14.8 vs. 4.2, P<0.001) and 2.9 times more citations in Google Scholar (17.8 vs. 6.0, P<0.001) when compared with papers with no "buzz."
Presence on Twitter was correlated with the number of academic citations of an article in radiation oncology. This suggests that Twitter is being utilized by the oncology community as a platform to discuss and disseminate high impact scientific articles. The correlation between Twitter and increasing the number of citations of an article through larger dissemination and exposure requires further studies.
本研究旨在探讨 Twitter 提及与放射肿瘤学文章的学术引用数量之间的相关性。
我们回顾了 2 种最重要的放射肿瘤学期刊（《肿瘤学年鉴》和《近距离放射治疗学》）以及发表于 2018 年 1 月至 2 月期间的排名前 10 的影响因子肿瘤学期刊中所有与放射肿瘤学相关的 178 篇临床手稿。我们利用 Scopus 和 Google Scholar 平台收集了引文记录，并使用“Altmetric Bookmarklet”记录文章被转发的次数。利用 χ2 检验比较组间分布，利用 Pearson 系数分析 Twitter 指标与学术引文之间的相关性。
总体而言，71%的文章至少被转发过一次。在 Google Scholar（r=0.55，P<0.001）和 Scopus（r=0.59，P<0.001）中，推文数量与引文数量之间存在显著相关性。具有预发表 Twitter“热议”（定义为在发表前有≥10 次转发的文章）的 11%的文章在 Scopus 中的引用次数增加了 3.6 倍（平均值：14.8 比 4.2，P<0.001），在 Google Scholar 中的引用次数增加了 2.9 倍（17.8 比 6.0，P<0.001），与无热议的文章相比。
在放射肿瘤学领域，Twitter 的存在与文章的学术引用数量相关。这表明 Twitter 正被肿瘤学界用作讨论和传播高影响力科学文章的平台。Twitter 与通过更大的传播和曝光增加文章引用数量之间的相关性需要进一步研究。
