Background: The aim of the study was to assess gender differences in the productivity, impact, collaboration pattern and author position of dentistry and oral sciences researchers in Nigeria. Methods: We examined the Web of Science (WoS) publication records of dentistry and oral sciences researchers to assess gender differences in productivity, impact, collaboration and authorship pattern (first authorship, last authorship and corresponding author). The analysis included the number of publications in journals ranked based on their quartile rating amongst the journals in the subject area (Q1-Q4). Chi square was used to make gender comparisons. Significance was set at >5%. Results: 413 unique authors published 1,222 articles on dentistry and oral sciences between 2012 and 2021. The number of WoS documents per female author was significantly higher than that per male author (3.7 vs. 2.6, p = 0.03). A non-significantly higher percentage of females authored papers in Q2 and Q3 journals and a higher percentage of males authored papers in Q4 journals. The number of citations per female author (25.0 vs. 14.9, p = 0.04) and the percentage of females listed as first authors (26.6% vs. 20.5%, p = 0.048) were statistically greater than men. The percentage of males listed as last authors was statistically greater than females (23.6% vs. 17.7%, p = 0.04). The correlation between the percentage of papers with researchers listed as first authors and that listed as last authors was not significant for males (p = 0.06) but was significant for females (p = 0.002). A non-significantly greater percentage of females were listed as corresponding authors (26.4% vs. 20.6%) and males were listed as international (27.4% vs. 25.1%) and domestic collaborators (46.8% vs. 44.7%). Also, there was no statistically significant gender difference in the proportion of articles published in open access journals (52.5% vs. 52.0%). Conclusion: Though there were significant gender differences in the productivity, impact, and collaboration profile of dentistry and oral sciences researchers in Nigeria, the higher female research productivity and impact may be driven by cultural gender nuances that needs to be explored further.
ABSTRACT
BACKGROUND: Bibliometric analysis has become popular in recent years, and increasingly more articles focusing on a particular disease are being published. The present study was performed to analyse the 100 most frequently cited papers in liver cancer (LC). METHODS: We searched the Thomson Reuters Web of Science database on 14 July 2018 to identify all potential manuscripts for this study. The search terms were 'liver cancer' and its synonyms. Manuscripts were listed in descending order by the total citations (TCs), and the 100 most frequently cited papers were identified and analysed by topic, journal, author, year and institution. RESULTS: We retrieved 235 687 papers from the Web of Science database. The TC of the 100 most frequently cited papers in LC ranged from 612 to 5358. The 100 papers were published in 31 journals and came from nine countries. The University of Barcelona published the highest number of papers and had the most TC. Ten authors published more than one paper. Treatment of LC was the most widely studied topic. A significant correlation was found between the journal's 2017 impact factor and the TC (P = 0.003). CONCLUSION: We assessed the landmark papers in the field of LC. These 100 most frequently cited papers reflect major advances and several hot topics in LC during the recent decades. Our study is of great value for young investigators, provides insights into the trends of LC and can guide directions for future academic research.
