This review is a bibliometric analysis of the contribution of neurosurgeons from the Kingdom of Saudi Arabia (KSA) to the international neurosurgical literature over the last three decades. The study aimed at determining changes in publication trends over time and assessing the impact of these changes on citation numbers. All publications in the PubMed-indexed neurosurgical journals that were authored by at least one Saudi neurosurgeon were selected. The articles were divided into two study groups according to publication year whether during the last decade (2011- 2020) or the previous two decades (1991- 2010). Changes in publication trends were determined by comparing the bibliometric characteristics of the articles in both groups. The impact of the changes on citation numbers was assessed by correlating the annual citation rates for the articles with their bibliometric qualities. A total of 352 publications were suitable for the review (200 articles published during 2011- 2020, and 152 during 1991- 2010). Temporal changes in the publishing journals and first authors' centres and regions were observed. The articles that were published in the last decade were associated with a significantly higher annual publication rate, a greater number of authors, centres, and countries, and a larger sample size compared to those published in the previous two decades. They also had a lower percentage of Saudi total and first authorship as well as a smaller proportion of case reports. The annual citation rate was significantly impacted by the duration from publication, sample size, and study type during both study periods. However, only during the last decade, the annual citation rate was positively influenced by the journal's impact factor, number of authors, centres, countries, and percentage of Saudi authorship. We conclude that KSA neurosurgeons' contribution to international neurosurgical journals had increased considerably over the last decade. The publications were authored by neurosurgeons from a wider range of centres and regions than in the past. A bigger portion of publications had become more multi-authored, multi-centred, and multi-national as well as reported larger sample sizes and lesser rates of case reports. The changes in publication trends correlated positively with the articles' annual citation rates. The findings could be considered encouraging.
本综述是一项文献计量分析，探讨了沙特阿拉伯王国（KSA）神经外科医生在过去三十年中对国际神经外科文献的贡献。该研究旨在确定出版趋势随时间的变化，并评估这些变化对引用次数的影响。我们选取了至少有一位沙特神经外科医生撰写的、被PubMed收录的神经外科期刊上的所有出版物。根据出版年份，将文章分为两个研究组，即过去十年（2011 - 2020年）和前两个十年（1991 - 2010年）。通过比较两组文章的文献计量特征来确定出版趋势的变化。通过将文章的年度引用率与其文献计量质量相关联，评估这些变化对引用次数的影响。共有352篇出版物适合本综述（2011 - 2020年发表200篇，1991 - 2010年发表152篇）。观察到了发表期刊以及第一作者所在中心和地区的时间变化。与前两个十年发表的文章相比，过去十年发表的文章年发表率显著更高，作者、中心和国家数量更多，样本量更大。沙特第一作者和总作者的比例也较低，病例报告的比例也较小。在两个研究期间，年度引用率均受到发表时长、样本量和研究类型的显著影响。然而，仅在过去十年中，年度引用率受到期刊影响因子、作者数量、中心数量、国家数量以及沙特作者比例的正向影响。我们得出结论，在过去十年中，沙特阿拉伯神经外科医生对国际神经外科期刊的贡献显著增加。与过去相比，出版物的作者来自更广泛的中心和地区。更大比例的出版物变得更加多作者、多中心、多国家，样本量更大，病例报告率更低。出版趋势的变化与文章的年度引用率呈正相关。这些发现可以说是令人鼓舞的。
