Abstract
AIMS: The association between the dissemination of scientific articles on Twitter and online visibility (including Altmetric score) is still controversial and the impact on citation rates has never been addressed for cardiovascular medicine journals. METHODS AND RESULTS: The ESC Journals Study randomized 696 papers published in the ESC Journals 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 if Twitter promotion was associated with an increase in citation rate (primary endpoint) and Altmetric score. This is a preliminary analysis of 536 articles (77% of total) published until December 2018 (therefore, papers published at least 6 months before collecting citation and Altmetrics data). In the analysis of the primary endpoint, Twitter promotion of articles was associated with a 1.43 (95% confidence interval 1.29-1.58) higher rate of citations, and this effect was independent of the type of article. Both Altmetric score and number of users tweeting were positively associated with the number of citations in both arms, with evidence of a stronger association (interaction) in the Twitter arm. CONCLUSION: Therefore, a social media strategy of Twitter promotion for cardiovascular medicine papers seems to be associated with increased online visibility and higher number of citations. The final analysis will include 696 papers and 2-year scientific citation rate and is estimated to be concluded in March 2021. Published on behalf of the European Society of Cardiology.
