There are errors in the published article. The first sentence of the subsection Relationship between Impact Factor and Average Number of Authors/Article in the Results section is incorrect. This sentence should read as follows: “A Pearson’s correlation between average authorship and impact factors for 47 journals published in 2013 (see Fig 7), showed a positive association (R = 0.65, P<0.001)”
The R value in the discussion should read R = 0.65.
