The present study examines Egyptian publications and research collaboration in health sciences using Thomson Reuters InCitesTM over the period of 1980-2014. Egypt, in clinical, pre-clinical and health, is ranked 44 among all countries according to the Web of Science documents (quantity) and total citations (quality). It is ranked at 40 and 55 respectively for international collaboration and the total number of highly cited papers. The total publications of Egyptian scientists in health sciences were 31 382, of which 27 693 articles were multi-authored, indicating a co-authorship ratio of 88 percent. It reveals that Egyptian scientists have a great tendency to collaborate. The collaborated papers show a greater citation impact, category normalized citation impact, and journal normalized citation impact and h-index compared to single authored papers. This reveals that the visibility and impact of co-authored papers are higher than that of single authored ones, as well as the visibility and impact of internationally co-authored publications are higher than the single authored or domestic papers. Egyptian scientists, in clinical, pre-clinical and health, had joint publications with their colleagues in 166 countries during the period under study. These countries were grouped according to geographic position, scientific capacity and economic development rate. The results show that Egypt’s main partners were USA, Saudi Arabia, Germany, England and Japan. In addition, Egyptian researchers mostly co-published with colleagues in Europe, scientifically advanced countries and high income countries. The findings could inform policy makers to develop research policies aiming to foster and support collaborations at all levels -researchers, institutions and countries.

埃及卫生科学家研究合作的文献计量模式和指标：1980

本研究使用 Thomson Reuters InCitesTM 调查了 1980 年至 2014 年期间埃及在健康科学领域的出版物和研究合作。根据 Web of Science 文献（数量）和总引用次数（质量），埃及在临床、临床前和健康方面在所有国家/地区中排名第 44。它在国际合作和高被引论文总数方面分别排名第 40 和第 55 位。埃及科学家在健康科学领域发表的论文总数为 31 382 篇，其中 27 693 篇为多作者，合着率为 88%。它表明埃及科学家有很大的合作倾向。与单一作者论文相比，合作论文显示出更大的引文影响、类别归一化引文影响、期刊归一化引文影响和 h 指数。这说明合着论文的知名度和影响力高于独着论文，国际合着论文的知名度和影响力也高于独着或国内论文。在研究期间，埃及科学家在临床、临床前和健康方面与他们在 166 个国家的同事联合发表了论文。这些国家根据地理位置、科学能力和经济发展速度进行分组。结果表明，埃及的主要合作伙伴是美国、沙特阿拉伯、德国、英国和日本。此外，埃及研究人员大多与欧洲、科学先进国家和高收入国家的同事共同发表论文。
