International trends of orthodontic publications: A bibliometric observational study of the last decade (2011-2020)

Diversity of authors in the British Journal of Orthodontics and Journal of Orthodontics over the last 50 years

AIMS

To explore any changes in the perceived gender and affiliation of first authors of papers published in the British Journal of Orthodontics (BJO) and Journal of Orthodontics (JO), over the last 50 years.

METHODS

Electronic hand searches of the BJO and JO from 1973 to 2021, were undertaken to identify research and clinical papers published the first volume of the BJO (1973-74) and then the first two volumes of each subsequent decade i.e. 1980-81; 1990-91 to 2020-21. Articles such as Editorials, Product Updates and Abstract summaries, were excluded.The perceived gender of the first author was identified from their forename, internet sources and/or personal knowledge, where possible. The country of the first author's affiliation was identified from the author details stated in the papers. The countries were then grouped into geographical areas.

RESULTS

A total of 385 papers were identified with a steady increase from 1973 to 2021. There was a statistically significant increase in papers published by authors who were perceived to be female (odds ratio 8.33; 95% CI 4.75, 14.64). The increase in papers published by non-UK affiliated first authors was significant (odds ratio 5.01; 95% CI 2.78, 9.02).

CONCLUSIONS

The Journal has seen a significant change, over the last 50 years, in its authorship profile from nearly exclusively male, UK based authors to more than 60% of published papers having a first author who was perceived as being female and 37% originating from outside the UK.
