The 100 top‐cited publications in psoriatic arthritis: a bibliometric analysis

Abstract

Background Citation analysis is a quantitative, bibliometric method that analyzes the frequency and pattern of citations in any given scientific discipline. Over the last two decades, the study of psoriatic arthritis has undergone substantial progress, which has enhanced our ability to assess and treat the disease, and yet an updated citation analysis that reflects these advances is lacking. Objective To highlight the scientific progress in psoriatic arthritis by identifying and analyzing the 100 top‐cited psoriatic arthritis articles from the last 40 years. Methods Publications on psoriatic arthritis were identified using the Scopus citation database and Web of Science. No date range limits were applied. Data on the 100 top‐cited publications were extracted and analyzed. Results Of the 100 top‐cited publications, the median number of citations per publication was 265.9. Articles originated from 29 different countries. Publication dates ranged from 1973 to 2014. The majority (n = 88) were published after 1994, and the greatest number of highly cited psoriatic arthritis publications were reported between 2001 and 2007 (n = 36). Journals with the highest number of top‐cited articles included Arthritis and Rheumatology (formerly Arthritis and Rheumatism) (n = 26), followed by Annals of Rheumatic Diseases (n = 21) and Journal of Rheumatology (n = 11). The top six journals with the most highly cited psoriatic arthritis articles were rheumatology journals, with the exception of the Journal of American Academy of Dermatology, a dermatology‐based periodical. General medical journals published only nine of the 100 top citations. Impact factors ranged from 2.133 to 44.002, with a mean impact factor of 9.103. There were five authors with 10 or more highly cited psoriatic arthritis publications and 30 authors with five or more of the top publications. Subgroup analysis of the top 25 articles included nine randomized clinical trials, nine observational studies, five reviews, and two guideline statements. Additional subgroup analysis identified the top five hallmark trials in the field. Key publications provided data on classification criteria, disease prevalence, patterns of clinical and radiographic presentation, disease outcomes, associated cardiovascular disease risk, immunologic features and HLA associations, and efficacy and therapeutic benefit of TNFα inihbitors, interleukin‐12/23 antagonists, and sulfasalazine. Conclusions The study of psoriatic arthritis is rapidly evolving. This bibliometric analysis delineates the landmark publications in psoriatic arthritis that have defined innovative therapeutic modalities and provided critical reviews, guidelines, and other key studies, which highlight the important progress made in the field.

The 100 top-cited studies on vaccine: a bibliometric analysis

“…This is entirely different from some other fields, only a few numbers of studies were published in the four famous journals. 16,17,24 Why most of the top-cited vaccine studies are published in highly IF journals, the reasons might be that vaccine researches covers all aspects of medicine, 2,9 which were quickly accepted by general medical journals. Besides, the most important vaccine researches should be published in the most famous medical journals, so that it can help the most populations.…”

“…15 Identification the milestones in a specific field can be done by analyzing the most cited study, especially by analyzing the 100 top-cited studies. 13,14,16,17 Assessment of the 100 top-cited studies had been conducted for various diseases including tuberculosis, 18 diabetes, 14 emergency medicine, 19 etc. However, there is no such study on the vaccine.…”

“…literature reviews reveal that there are bibliographical analyses on many topics. among these, there are various topics such as conventional and complementary medicine (4), anaesthesia reanimation (5), phys-iotherapy and rehabilitation (6), orthopaedics 7, spinal surgery (8), headache (9), neurorehabilitation (10) and psoriatic arthritis (11). However, literature reviews on fibromyalgia indicate that there is no extensive study on the top cited articles in this area.…”

The 100 top-Cited Studies on Ebola: A Bibliometric Analysis

“…Like other previous bibliometric analyses, our study also has some limitations [16,17]. First, citation analysis was based on one database, the Web of Science; thus, some essential papers indexed by other databases might have been missed [16,22]. The citation numbers therefor might be misleading [30], owing to self-citations, time of publications, among other factors.…”

“…Identi cation of milestones in a particular eld can be done by analysing the most cited studies, especially the 100 top-cited studies [13][14][15]. Evaluation of the 100 top-cited studies had been conducted for various medical elds and diseases, including tuberculosis [15], diabetes [14], Vaccines [16], Arthritis [17], among others. However, there is no such study conducted on Ebola.…”
