Comparison of publication trends for general and gender-specific literature. (A) Absolute numbers of gender-related yearly publications within the nine disciplines analysed are presented (n = 3,466). Publications are limited between 1975 and 1989, while they increase more markedly thereafter. (B) Publications trends in the field of Myocardial infarction (MI) and Asthma between 1976 to 1977 and 2008. Black squares indicate the total yearly number of publications within the field; black dots represent the number of sex/gender-specific publications within the field; red squares indicate the log(2) ratio between sex/gender literature and general literature. The noted increase after 1990 is recapitulated by these single diseases. Publications increase more in the field of gender medicine compared to overall trends (as expressed by the ratio between the trends).
