Gender specificity of citations and scholarly productivity. (A) The descendingly ordered citation rates show that articles with male key authorships are slightly more frequently cited than articles with female key authorships. The mean citation rate of 9.2 citations/article is depicted by a dotted line (Kruskal-Wallis test, *P<0.05, **P<0.01). (B) Average citation rates of ungrouped articles (bars) and articles that were grouped by the gender of their key authorships (lines), depicted as a function of the number of authors. Statistically, the citation rate of an article is higher the more authors are involved. The gender-specific differences in citation rates are not preserved across the different levels of author count. (C) Gender-specific distribution of the article count per author. Women dominate the subgroups ’author has one or two article(s)'. All other subgroups are characterised by a relatively over-representation of male authors. This finding correlates with the higher productivity of male authors, as 52.8% male authors are responsible for 57.0% of all authorships.
