Time trend of female authorships (FAP) on the global level. (A) The relative frequency of FAP (bottom), the pattern of female authorship odds ratios (FAORs) (with FAOR-triplet, top) and its associated Prestige Index (PI) are depicted by year and averaged over time. The averaged FAOR distribution is characterised by the FAOR-pattern (+, +, −), ie, women have significantly higher odds for first authorships and coauthorships and significantly lower odds for last authorships. The slightly negative PI indicates a lack of prestigious authorships held by women. (B) The FAP exhibits a relatively high increase as documented by its average annual growth rate (AAGR) of 1.74% per year with the highest rate for last authorships (2.97%). Overall, this led to more gender neutrality in authorships odds during the recent years.
