 JAAD Scopus bibliometry dermatology research publications articles bibliometrics

Recently in dermatology, the most influential scientists were reported [1,2]. Similarly, after analyzing the publications over 10 years (2011-2020), the top authors in the Journal of the American Academy of Dermatology (JAAD) were also described [3]. In this letter, we are reporting for the first time the top three authors in three world-class journals (ie, JAAD, JAMA Dermatology [JAMA-D], and American Journal of Clinical Dermatology [AJCD]). On July 24, 2022, the data was retrieved from the Scopus database, and the analysis was performed on RStudio (Bibliometrix/Biblioshiny) software (RStudio, PBC). We only analyzed research articles and excluded the year 2022. Scopus has been covering JAAD, JAMA-D and AJCD since 1979, 2013 and 2000, respectively. In total:

JAAD published 17,065 research articles. A total of 93 authors published at least 30 articles (for a total of 2732 articles). In these publications, the authors were from 2307 universities in 65 countries.

JAMA-D has published 1200 articles, of which 5975 authors from 1900 universities in 56 countries have contributed.

AJCD has published 492 articles. In all publications, 1866 authors were from 838 universities in 45 countries.

During the analysis, authors were included from JAMA-D and AJCD if they had published at least 5 research articles.

There are several bibliometric indicators that can be used for analysis. For example, the h-index considers both the number of publications and citations. In other words, a dermatologist with 5 articles with 5 or more citations (each) will have an h-index of 5. The g-index is another interesting indicator. It represents the highest number “g” of articles that together received g2 or more citations. A g-index of 10 indicates that the top 10 publications have been cited at least 100 times (102). The m-quotient (or m-index) considers both the h-index and the number of years. The m-index can be obtained by dividing the h-index by the number of years since the first publication of an author. For example, an h-index of 10 for an individual over 5 years means that the m-quotient is 2.

Our results differed from earlier reports [1-3], as they ranked the authors on the basis of the total number of publications and the h-index. We highlighted the most influential authors in all 3 journals on the basis of the total number of publications, total citations, h-index, g-index, and m-index. The data is presented in Table 1. We also provide the list of the top 10 most productive universities and countries (Table 2).

The major limitations of this letter are name changes (variations in initials) and duplication of common names (authors and universities), which are not addressed. This may affect the ranking. We only relied on Scopus; other databases were not included in this study.
