To evaluate whether a citation advantage exists for open access (OA) publications in gynecologic oncology.
A cross-sectional study of research and review articles published in the () and in during 1980-2022. Bibliometric measures were compared between OA publications and non-OA publications. The role of authors in low/middle-income countries was assessed. We analyzed article characteristics associated with a high citations per year (CPY) score.
Overall, 18 515 articles were included, of which 2398 (13.0%) articles were published OA. The rate of OA has increased since 2007. During 2018-2022, the average proportion of articles published OA was 34.0% (range 28.5%-41.4%). OA articles had higher CPY (median (IQR), 3.0 (1.5-5.3) vs 1.3 (0.6-2.7), p<0.001). There was a strong positive correlation between OA proportion and impact factor; - r(23)=0.90, p<0.001, - r(23)=0.89, p<0.001. Articles by authors from low/middle-income countries were less common among OA articles than among non-OA articles (5.5% vs 10.7%, p<0.001). Articles by authors from low/middle-income countries were less common in the high CPY group than for articles without a high CPY score (8.0% vs 10.2%, p=0.003). The following article characteristics were found to be independently associated with a high CPY: publication after 2007, (adjusted odds ratio (aOR)=4.9, 95% CI 4.3 to 5.7), research funding reported (aOR=1.6, 95% CI 1.4 to 1.8), and being published OA (aOR=1.5, 95% CI 1.3-1.7). Articles written by authors in Central/South America or Asia had lower odds of having high CPY (Central/South America, aOR=0.5, 95% CI 0.3 to 0.8; Asia, aOR=0.6, 95% CI 0.5 to 0.7).
OA articles have a higher CPY, with a strong positive correlation between OA proportion and impact factor. OA publishing has increased since 2007, but articles written by authors in low/middle-income countries are under-represented among OA publications.
评估妇科肿瘤学领域的开放获取（OA）出版物是否具有引文优势。
对 1980 年至 2022 年期间发表在《妇产科》和 中的研究和综述文章进行了横断面研究。比较了 OA 出版物和非 OA 出版物的文献计量指标。评估了来自中低收入国家作者的作用。分析了与高每年引文数（CPY）评分相关的文章特征。
总体而言，共纳入 18515 篇文章，其中 2398 篇（13.0%）为 OA 出版物。自 2007 年以来，OA 出版的比例有所增加。2018-2022 年期间，OA 出版的文章平均比例为 34.0%（范围为 28.5%-41.4%）。OA 文章的 CPY 更高（中位数（IQR），3.0（1.5-5.3）比 1.3（0.6-2.7），p<0.001）。OA 比例与影响因子之间存在很强的正相关关系； - r（23）=0.90，p<0.001， - r（23）=0.89，p<0.001。来自中低收入国家的作者撰写的文章在 OA 文章中比在非 OA 文章中更为少见（5.5%比 10.7%，p<0.001）。来自中低收入国家的作者撰写的文章在高 CPY 组中比没有高 CPY 评分的文章更为少见（8.0%比 10.2%，p=0.003）。具有高 CPY 的文章的以下特征与独立相关：发表于 2007 年后（调整后的优势比（aOR）=4.9，95%CI 4.3-5.7），有研究资金报告（aOR=1.6，95%CI 1.4-1.8）和 OA 出版（aOR=1.5，95%CI 1.3-1.7）。来自中美洲/南美洲或亚洲的作者撰写的文章获得高 CPY 的可能性较低（中美洲/南美洲，aOR=0.5，95%CI 0.3-0.8；亚洲，aOR=0.6，95%CI 0.5-0.7）。
OA 文章的 CPY 更高，OA 比例与影响因子之间存在很强的正相关关系。自 2007 年以来，OA 出版的比例有所增加，但来自中低收入国家的作者撰写的文章在 OA 出版物中所占比例较低。
