The association between the dissemination of scientific articles on Twitter and online visibility (as assessed by the Altmetric Score) is still controversial, and the impact on citation rates has never been rigorously addressed for cardiovascular medicine journals using a randomized design. The ESC Journals Study randomized 695 papers published in the ESC Journal Family (March 2018-May 2019) for promotion on Twitter or to a control arm (with no active tweeting from ESC channels) and aimed to assess whether Twitter promotion was associated with an increase in citation rates (primary endpoint) and of the Altmetric Score. This is the final analysis including 694 articles (one paper excluded due to retraction). After a median follow-up of 994 days (interquartile range: 936-1063 days), Twitter promotion of articles was associated with a 1.12 (95% confidence interval: 1.08-1.15) higher rate of citations, and this effect was independent of the type of article. Altmetric Attention Score and number of users tweeting were positive predictors for the number of citations. A social media strategy of Twitter promotion for cardiovascular medicine papers seems to be associated with increased online visibility and higher numbers of citations.
Twitter 上科学文章的传播与在线可见度（通过 Altmetric 分数评估）之间的关联仍存在争议，并且使用随机设计，心血管医学期刊的引文率影响从未得到严格评估。ESC 期刊研究将 2018 年 3 月至 2019 年 5 月期间在 ESC 期刊系列中发表的 695 篇论文随机分配到 Twitter 推广组或对照组（ESC 频道无主动推文），旨在评估 Twitter 推广是否与引文率（主要终点）和 Altmetric 分数的增加相关。这是包括 694 篇论文的最终分析（一篇论文因撤回而被排除在外）。中位随访 994 天（四分位距：936-1063 天）后，文章的 Twitter 推广与引文率提高 1.12（95%置信区间：1.08-1.15）相关，这种效果独立于文章类型。Altmetric 关注度得分和推文用户数量是引文数量的正预测因子。针对心血管医学论文的 Twitter 推广社交媒体策略似乎与在线可见度的提高和引文数量的增加有关。
