    OBJECTIVE The aim of this study was to examine female authorship in research from collaborations between high-income countries (HICs) and lower-middle-income and low-income countries (LMICs/LICs) across two time periods: 2018–2020 and 2021–2023. METHODS A bibliometric analysis of neurosurgical research articles from the Scopus database, published between 2018 and 2023, was performed to investigate collaboration trends between HICs and LMICs/LICs. Only neurosurgical publications were included, and female authors were identified based on names traditionally associated with female gender identity, verified through online searches and tools such as Genderize.io. Articles with more than 25 authors, commentaries, letters, and news items were excluded to ensure a focus on original research. The selected articles spanned various neurosurgical specialties and were restricted to English-language journals with an impact factor greater than 1. The country affiliations of first, corresponding, and last authors were categorized using the 2018 World Bank classification to understand collaboration patterns across income levels. RESULTS The analysis revealed a steady increase in neurosurgical publications from 2018 to 2023, with a notable rise in the second triennium (2021–2023). Authors from HICs consistently held the majority of first, corresponding, and last authorship positions. Concerning first authorship, authors with affiliations from HICs increased from 66% in the first triennium to 75% in the second. Similarly, corresponding authors from HICs increased from 75% to 82% over the same period. Male authors dominated all key authorship roles, with 127 male-led first authorships compared with 46 female-led first authorships in the second triennium. This male predominance persisted in corresponding and last author roles as well. CONCLUSIONS Global neurosurgical research is growing but significant gender disparities persist, especially in LMICs/LICs, with female researchers underrepresented in key authorship roles, requiring targeted efforts to address systemic barriers and promote gender equity in academic leadership.

    PURPOSE: To examine 10-year trends in gender representation in speaking roles at major spine conferences. BACKGROUND CONTEXT: Medical conferences play an important role in career opportunities. There is little analysis on gender representation of major spine conferences despite several studies demonstrating gender disparities within spine surgery. STUDY DESIGN: Observational study. SAMPLE: A total of 20,181 abstract speakers across 10 years of academic conferences for 6 spine societies. OUTCOME MEASURES: Percent of female abstract presenters. MATERIALS AND METHODS: We collated the annual meeting programs of six major spine conferences (North American Spine Society (NASS), Scoliosis Research Society (SRS), International Meeting on Advanced Spine Techniques (IMAST), Global Spine Congress (GSC), American Association of Neurological Surgeons/Congress of Neurological Surgeons (AANS/CNS) Spine Summit, and the Cervical Spine Research Society (CSRS)) dating from 2013 to 2022. Departmental websites, society webpages, or personal social media were identified for images or the use of gendered pronouns in order to determine speaker gender for each speaker type. All categorical variables were compared using Pearson chi-square analysis. RESULTS: Women constituted 1,816 (9.0%) of all 20,181 identified conference speakers. Female representation was highest at NASS (N=680, 12.2%) but lowest at CSRS (6.6%) and GSC (7.1%). Spine Summit (7.4%), IMAST (9.92%), and GSC (9.87%) demonstrated the largest annual percent increases in female representation. Institutions in Middle East and Africa (1.4%), and Central and South America (1.8%) supported the lowest percent of female speakers. Women were significantly less likely to be speakers or moderators/course faculty than to be podium abstract presenters (p<.001). The percent of women as invited speakers (10.4% vs 5.5%, p=.001) and moderators (11.4% vs 3.7%, p<.001) increased significantly over the study period, with annual increases of 8.8% and 20.8%, respectively, from 2013 to 2022 (p<.001). CONCLUSIONS: While academic spine societies have made significant progress in promoting gender representation, especially among invited speakers and session moderators, women continue to be underrepresented compared to the percent of women in orthopedic surgery and neurosurgery

    OBJECTIVE: A meta-analysis was performed to understand disparities in the representation of female authorship within the neurosurgical literature and implications for career advancement of women in neurosurgery. METHODS: Author names for articles published in 16 of the top neurosurgical journals from 2002 to 2019 were obtained from MEDLINE. The gender of each author was determined using automated prediction methods. Publication trends were compared over time and across subdisciplines. Female authorship was also compared to the proportionate composition of women in the field over time. RESULTS: The metadata obtained from 16 major neurosurgical journals yielded 66,546 research articles. Gender was successfully determined for 96% (127,809/133,578) of first and senior authors, while the remainder (3.9%) were unable to be determined through prediction methods. Across all years, 13.3% (8826) of articles had female first authorship and 9.1% (6073) had female senior authorship. Female first authorship increased significantly over time from 5.8% in 2002 to 17.2% in 2019 (p < 0.001). Female senior authorship also increased significantly over time, from 5.5% in 2002 to 12.0% in 2019 (p < 0.001). The journals with the highest proportions of female first authors and senior authors were the Journal of Neurosurgery: Pediatrics (33.5%) and the Asian Journal of Neurosurgery (23.8%), respectively. Operative Neurosurgery had the lowest fraction of female first (12.4%) and senior (4.7%) authors. There was a significant difference between the year-by-year proportion of female neurosurgical trainees and the year-by-year proportion of female neurosurgical first (p < 0.001) and senior (p < 0.001) authors. Articles were also more likely to have a female first author if the senior author of the article was female (OR 2.69, CI 2.52-2.86; p < 0.001). From 1944 to 2019, the Journal of Neurosurgery showed a steady increase in female first and senior authorship, with a plateau beginning in the 1990s. CONCLUSIONS: Large meta-analysis techniques have the potential to effectively leverage large amounts of bibliometric data to quantify the representation of female authorship in the neurosurgical literature. The proportion of female authors in major neurosurgical journals has steadily increased. However, the rate of increase in female senior authorship has lagged behind the rate of increase in first authorship, indicating a disparity in academic advancement in women in neurosurgery.

    OBJECTIVE: Gender inequalities persist in several areas of medicine, despite the growing number of female doctors and medical students. In this study, we aimed to reveal the gender inequality in the top journals' editorial boards and national societies' leadership positions in the field of neurology and neurosurgery. METHOD: This is a cross-sectional study that uses public information accessed through the internet via journals' and academic societies' public websites. The medical journals are selected and included according to their h5-index in the field of neurology and neurosurgery. We evaluated the gender composition of the editorial boards and academic societies' leadership positions. RESULTS: The female editorial board member ratio was 44.0% in the top 10 neurology journals. However, this ratio was significantly decreased to 29.7% in the other journals(P < 0.001). The top 10 neurosurgery journals had a female editorial board member ratio of 13.7%. This ratio was significantly decreased to 5.3% in the other 10 journals with lower h5-index(P < 0.001). A significantly lower number of female individuals are present in the editorial boards of the neurosurgery journals than in neurology(P < 0.001). The female president or delegate ratio was 19.3% in the World Federation of Neurology-affiliated countries, and it was 4% in the World Federation of Neurosurgical Societies-affiliated countries. CONCLUSIONS: In conclusion, there is a significant gender inequality among editorial board members. The position of neurosurgical societies and journals is far different than the field of neurology. Furthermore, these findings should be evaluated as a continuum of the gender inequality in the professional societies' executive boards and delegates representing the national academical community.
