Fox CS, Bonaca MA, Ryan JJ, et al. A randomized trial of social media from Circulation. Circulation e-pub November 18, 2014
In order to determine whether social media exposure to original articles improves article impact metrics, the authors conducted a randomized trial of social media with a focus on short-term impact. Articles from Circulation were randomly assigned to be promoted through the official journal's social media accounts (Facebook and Twitter feeds). The results showed that this social media strategy did not increase the number of times an article was viewed.
