Do co-published articles get more citations?

Collaboration does not render in high impact publications per se, but high quality collaborations can leverage the impact of the research.

Statistically the average number of citations increases with increasing author group size (or the number of organizations that the authors are affiliated to). However, the distribution of citations between articles are highly skewed, some publications get a lot of citations and a large number of publications get none or just a few citations also when the number of authors is large. The correlation coefficient (r) between the number of authors and the citation rate is therefore low. Hence, the number of authors is not a good predictor of the number of citations, since there are publications with one or a few authors that get high impact and a lot of co-authored articles that does not. Nevertheless, since the average citations rate is higher for co-published articles one can draw the conclusion that collaboration can have some positive effect on citations rates and thus on the impact of the research.
