Looking beyond traditional metrics in orthodontics: An altmetric study on the most discussed articles on the web

Abstract

Objective: To evaluate the online visibility of the most popular orthodontic articles inWeb platforms in relation to publication details and citations. Materials and Methods: Altmetric Explorer (Altmetric LLP, London, UK) was searched for articles published in 11 orthodontic journals without time limits in publication and citation on social media. The 200 articles with the highest Altmetric Attention Score (AAS) were collected and screened for data related to publication (date, journal, access), authorship (number of authors, affiliation and origin of the corresponding author), and research (type, subject, funding). Citation counts were harvested from Scopus. Results: The top 200 articles presented a median AAS of 8.0 (range: 5.0–196.0), and were mostly bookmarked in Mendeley (median: 16.6 references; range: 0–199.0). American Journal of Orthodontics & Dentofacial Orthopedics, European Journal of Orthodontics and The Angle Orthodontist contributed 86 per cent of the total number of research outputs. Studies investigating socio-demographics had significantly higher AAS compared to diagnostic studies (median AAS: 19.0; range: 7.0–34.0; versus median AAS: 6.0; range: 5.0–10.0. No other study parameter was found to be statistically significant. AAS did not correlate to the number of citations as reported in Scopus. Limitations: The early stage of altmetrics and their complementary role in assessing together with the citation-based metrics the research impact need to be acknowledged in the interpretation of the results. Conclusions: Visibility of orthodontic articles on the Web is not significantly correlated with citations. Studies on socio-demographics had significantly higher number of online mentions. More constructive online presence of orthodontic journals is needed to reinforce dissemination of research data among scholars and non-scholars.
