- Scientific articles that were cited in the newly written Wikipedia articles in the treatment group saw a e$^{0.6490}$ - 1 = 91% increase compared to references listed in the control group articles
- Exposure through publishing new articles onto Wikipedia also increased citations by 2$^{0.1762}$ – 1 = 13%. 
- Scholars are more likely to first consult Wikipedia and references listed in specific articles before conducting additional research and publishing their own findings in academic journals (more article views mean those references are cited more frequently outside of Wikipedia)

University of Michigan - Ann Arbor

- Studied causation of Wikipedia citations on the scientific community between 2013 and 2016
- Each of the newly written Wikipedia articles had 2 to 3 academic citations on average
- Same randomization as actual experiment for sorting articles into treatment and control groups 
- Used Poisson and Negative Binomial regressions to test whether references in Wikipedia articles affect the number of times those sources are cited in other academic publications
