目的分析10种外科学综合类期刊零被引论文的特征。方法选择《2016年版中国科技期刊引证报告(核心板)》10种外科学综合类期刊,在中国知网CNKI中检索2011年发表的零被引论文,分析10种期刊零被引论文的作者数量、第一作者所属机构、基金资助情况、论文篇幅和类型。结果零被引论文共435篇,零被引率为7.0%~20.0%,其中《中国实用外科杂志》居首位,影响因子排第2位,最低的是《中国微创外科杂志》。署名2~5位作者的零被引论文比例最高,占75.9%(330/435),1位作者零被引论文比例最低,占8.5%(37/435)。零被引论文第一作者所属机构中,省部级医院/医科大学附属医院所占比例最高(49.0%),其次为市级医院/医学院附属医院(42.3%)。零被引论文无基金所占比例最高,达87.1%(379/435),国家级基金所占比例最低,为3.9%(17/435)。435篇零被引论文的平均篇幅是2.3页。零被引论文类型临床研究所占比例最高,占57.9%(252/435),其次为病例报告,占22.8%(99/435)。结论 10种外科学综合类期刊2011年零被引率与影响因子关系不大。零被引论文中,署名2~5位作者占大多数,第一作者所属机构以省市级医院为主。零被引论文无基金资助占大多数,论文类型以临床研究和病例报告为主。

Objective To analyze the characteristics of non-cited papers in ten surgical comprehensive journals. Methods Ten surgical comprehensive periodicals indexed in“2016 edition of China Scientific and Technical Citation Reports”were selected.The non-cited papers published in 2011 were searched and downloaded from the CNKI database.The number of authors,first author affiliation,paper foundation,and article types and length were analyzed. Results The number of non-cited papers in the ten surgical comprehensive periodicals was 435,with non-cited rates being 7.0%-20.0%.The non-cited rate of Chinese Journal of Practical Surgery was the highest,whose impact factor was at the second place,while Chinese Journal of Minimally Invasive Surgery was the lowest.Articles having 2-5 co-authors had the maximum proportion(75.9%)of non-cited rate,while articles having only one author had the minimum proportion(8.5%).Concerning first author affiliations of non-cited papers,provincial/medical university affiliated hospitals accounted for 49.0%,followed by municipal/medical college affiliated hospitals,42.3%.Unfunded articles had the highest proportion in the 435 non-cited papers,up to 87.1%(379/435),and articles funded by national foundation accounted for 3.9%(17/435).The average length of 435 papers was 2.3 pages.Among the non-cited papers,clinical study accounted for 57.9%(252/435),followed by case report,accounting for 22.8%(99/435). Conclusions Non-cited rates of ten surgical comprehensive periodicals in 2011 has little relationship with their impact factors.Among non-cited papers,articles having 2-5 authors predominate,and most first authors are from provincial or municipal hospitals.Unfunded articles account for a majority of proportion,and article types are mainly clinical research and case report.
