Sex Disparities in Ophthalmic Research: A Descriptive Bibliometric Study on Scientific Authorships.

ABSTRACT:

Importance

Previous studies examined sex distributions in different medical faculties, especially because increasingly more women entered the medical field in recent decades. Little is known at present about the female representation in ophthalmic research.

Objective

To clarify sex equalities in ophthalmic research by evaluating the representation of female authorships.

Design and setting

This bibliometric analysis included original English-language articles published in ophthalmologic journals indexed in the Web of Science from January 2008 to August 2018. Authorships were assigned by sex according to first name.

Main outcomes and measures

Outcomes included the proportion of female authorships, odds ratios of women holding prestigious first and last authorships compared with men (measured by the prestige index), citation rates, a productivity analysis, and cross-journal and transnational female representation within ophthalmic research. The hypothesis was formulated during data collection.

Results

Bibliometric data were abstracted from 87 640 original articles published in 248 ophthalmologic journals. Of 344 433 total authorships, female scholars held 34.9% (120 305 of 344 433) of all authorships, 37.1% (24 924 of 67 226) of first authorships, 36.7% (77 295 of 210 372) of coauthorships, and 27.1% (18 086 of 66 835) of last authorships. The female-to-male odds ratio was 1.12 (95% CI, 1.10-1.14) for first authorships, 1.20 (95% CI, 1.18-1.22) for coauthorships, and 0.63 (95% CI, 0.62-0.64) for last authorships, with annual growth rates of 1.6% overall, 1.6% for first authorships, 1.3% for coauthorships, and 2.5% for last authorships. Women were underrepresented in prestigious authorships (prestige index = -0.22). The underrepresentation remains almost stable for articles with many authors (prestige index = -0.17 for articles with >9 authors per article). Articles with female key authors were cited slightly less frequently (95% CI for female vs male authors, 10.8-11.0 vs 11.5-11.7 citations/articles). Women published fewer papers than men (42.5% [n = 41 383]; women held 34.9% [n = 120 207] of the authorships), show cross-journal uniformity and differences among single countries (change in prestige index = 0.66 vs 1.96). Overall, 44.1% of female authorships and a sex-neutral distribution of prestigious authorships are prognosticated for 2028.

Conclusions and relevance

This algorithm analysis suggests the integration of women into ophthalmic research is average compared with other disciplines. A sex-specific gap exists for last authorship, suggesting career inequalities. With a growing number of female researchers in ophthalmology, the number of women in senior ranks may increase in the future.

Project description:ObjectiveThe present study aims to elucidate the state of gender equality in high-quality dermatological research by analysing the representation of female authorships from January 2008 to May 2017.DesignRetrospective, descriptive study.Setting113 189 male and female authorships from 23 373 research articles published in 23 dermatological Q1 journals were analysed with the aid of the Gendermetrics Platform.Results43.0% of all authorships and 50.2% of the firstauthorships, 43.7% of the coauthorships and 33.1% of the last authorships are held by women. The corresponding female-to-male ORs are 1.41 (95% CI 1.37 to 1.45) for first authorships, 1.07 (95% CI 1.04 to 1.10) for coauthorships and 0.60 (95% CI 0.58 to 0.62) for last authorships. The annual growth rates are 1.74% overall and 1.45% for first authorships, 1.53% for coauthorships and 2.97% for last authorships. Women are slightly under-represented at prestigious authorships compared with men (Prestige Index=-0.11). The under-representation remains stable in highly competitive articles attracting the highest citation rates, namely, articles with many authors and articles that were published in highest-impact journals. Multiauthor articles with male key authors are only slightly more frequently cited than those with female key authors. Women publish slightly fewer papers compared with men (47.2% women hold 43.0% of the authorships). At the level of individual journals, there is a high degree of uniformity in gender-specific authorship odds. By contrast, distinct differences at country level were revealed. The prognosis for the next decades forecasts a consecutive harmonisation of authorship odds between the two genders.ConclusionsIn high-quality dermatological research, the integration of female scholars is advanced as compared with other medical disciplines. A gender gap consists mainly in the form of a career dichotomy, with many female early career researchers and few women in academic leadership positions. However, this gender gap has been narrowed in the last decade and will likely be further reduced in the future.

Project description:ObjectiveSubstandard and falsified (SF) medical products are a global public health threat. The presence and spread of SF drugs negatively affect (1) patients' safety and health outcomes, (2) national economy, (3) public trust in the healthcare system, and (4) the international fight against serious health challenges such as malaria and antimicrobial resistance. The objective of the current study was to investigate and provide a snapshot analysis of the evolution and developmental patterns of global research publications on SF products.MethodsA bibliometric approach was adopted using terms such as fake, falsified, counterfeit, substandard, and others. No language restriction was made. The study period was from 1900 up to 2020. The search strategy was validated and implemented using Scopus database.ResultsThe search strategy retrieved 978 documents authored by 2861 researchers from 100 different countries and published in 421 different journals. The retrieved documents received 11,237 citations (11.5 citations per document) with an H-index of 53. The 978 documents retrieved from Scopus were published from 1961 to 2020, giving an average of 16.6 publications per year. The present study indicated that research on SF medical products: (a) has experienced a steep growth from 2001 to 2012 followed by a steady-state growth; (b) was disseminated in a wide range of journals, mainly in the fields of the pharmaceutical industry, analytical chemistry, public health, infectious diseases, and internal medicine; (c) was published by scholars with diverse and distant geographical backgrounds; (d) was mainly produced in the United States, United Kingdom, and Germany; (d) has fragmented research networks and a limited number of researchers per network; (e) has limited cross-country collaboration except for that between the US and the UK in one hand and countries in the Mekong region in the other hand; (f) emphasized on medications related to malaria and sexual stimulants; and (g) received relatively inadequate funding.ConclusionsResearch on SF medical products is important and should remain a priority to ensure good quality of medications. Research activity in the field needs to be encouraged in world regions such as Africa and the Middle East where drug regulations are unsatisfactory and cross-border trade of illegal medications is common.
