ObjectiveTo analyse the hundred top-cited articles in obstructive sleep apnea hypopnea syndrome (OSAHS), and summarize the development trend of OSAHS research.MethodsWe searched the Web of Science core collection for all published articles on OSAHS or sleep disorders from January 1st, 1992 to May 23th, 2018. The hundred top-cited articles with the most frequent citation were selected. The publication time, country of origin, journal, institution, professional field of corresponding author, funding type, publication type, etc. were analyzed.ResultsThe hundred top-cited articles were published between 1992 and 2013, with 300～5 980 citations and a total of 65 719 citations. The main types of articles were clinical studies (73 articles), reviews (20 articles), guidelines (4 articles) and basic research (3 articles). Fourteen authors published more than one first-author paper, and fifteen authors published more than one articles as corresponding authors. These authors were distributed across 22 subject areas. The most cited country was the United States (60 articles), and the most cited institution was the University of Wisconsin (10 articles). The hundred top-cited articles were published in 31 journals, most of which were cited less than 1 000 times, and a few articles were cited more than 2 000 times.ConclusionsOSAHS has attracted much attention in respiratory medicine, neurology, epidemiology and other fields, and many articles about clinical research types of OSAHS have been cited. In addition, most of the highly cited articles in the OSAHS field come from the developed countries; our country needs to devote more resources to OSAHS research.
ObjectiveTo investigate the annual publication volume, paper type distribution, journal quartile distribution, and citation status of SCI journal papers published by West China Hospital, Sichuan University, to provide a reference for optimizing the publication-based research evaluation system. MethodsA cross-sectional study was conducted. The Web of Science Core Collection was electronically searched to retrieve all papers affiliated with West China Hospital, Sichuan University. After screening, SCI journal papers up to December 31, 2024, in which the first author’s first affiliation was West China Hospital, Sichuan University published were included. Citation information as of December 31, 2024 was further obtained from the Web of Science Core Collection. R 4.2.2 software was used to analyze the annual quantity, journal quartile, paper type and citation distribution of SCI papers. ResultsA total of 38 005 papers were included. Original articles accounted for the highest proportion (62.06%), followed by reviews (17.66%), meeting abstracts (10.16%), letters (6.17%), and editorials (3.95%). Overall, 55.11% of the papers were published in JCR Q1 journals, and the proportion of Q1 papers showed a trend of initial decline followed by a rise over time. By the end of 2024, the total number of citations all included papers was 534 338, with an average number of citations of 14.06 per paper. The proportion of papers that received no citations within 2 years of publication was 29.65%. The 2-year average citation frequency ranked reviews (11.18) > original articles (5.99) > editorials (1.78) > letters (1.23) > meeting abstracts (0.23), and ranked as Q1 (7.61) > Q2 (4.28) > Q3 (3.18) > Q4 (1.56) when classified by JCR quartile. However, the 2-year citation rate was Q2 (75.67%) > Q3 (71.00%) > Q1 (68.78%) > Q4 (53.98%). ConclusionThe annual publication volume, the proportion of high-level Q1 journal papers, and the citation rate and average citation frequency of West China Hospital all showed an increasing trend. Nevertheless, structural problems such as a high proportion of uncited papers and a lack of high-impact papers remain.
