The longitudinal relationship between social media activity and article citations in the journal Gastrointestinal Endoscopy

Abstract Background and Aims Social media activity in the area of scientific journal publications has increased significantly over the last decade. Several studies have suggested that journal article citations can be positively impacted by an increase in social media activity. Preliminary data have also suggested that published articles in the field of gastroenterology and hepatology which were discussed on Twitter were independently associated with higher citation rates compared with those that were not. Gastrointestinal Endoscopy (GIE) is the most widely cited endoscopy-focused journal in the world. We aimed to assess the association of social media exposure of published articles in GIE and its impact on article citations. Methods Data regarding journal article publication status, number of citations per article, and social media exposure per article using Altmetric data were collected from the publisher. All original articles published in GIE from 2000 to 2016 were reviewed. Editorials, case reports, and other non-research correspondence were excluded. Multivariable linear regression was used to assess for independent Altmetric predictors of higher citation rates over time. Logistic regression was used to assess the impact of an article mention on various social media platforms and whether it was cited during the study period. Results A total of 2,361 original research articles were evaluated. 2,050 (86.8%) articles were cited at least once during the follow-up period. Mean number of citations per article was (16.8±23). The average Altmetric Attention score was 2.0±13. The most profound independent predictor of article citation was whether an article was tweeted (OR, 14.2; 95% CI, 8.93-22.45). Other predictors include Facebook posts (OR, 1.08; 95% CI, 1.03-1.51) and number of Mendeley readers (OR, 1.359; 95% CI, 1.28-1.45). On multivariable linear regression, number of Tweeters (β 2.3, p=0.022), F1000 reviews (β 5.87, p Conclusions For original articles published in GIE , there was a strong association between social media exposure on Twitter and rates of journal article citations. To a lesser degree, Facebook posts and Mendeley readers also were associated with a higher rate of article citations. This could represent both cause and effect and may be representative of higher-quality articles being more commonly mentioned on social media by third-party users. A randomized-controlled study evaluating different degrees of social media exposure on individual articles could be considered to further assess for causality.
