Objective: This study aims to identify determinants of high impact, measured by Impact Factor (IF) and Eigenfactor score, among otolaryngology journals.
Methods: Bibliometric data of "otorhinolaryngology" journals were collected from the Journal Citation Reports (JCR) database. For the years 2009-2020, we collected normalized Eigenfactor score, 5-year IF, immediacy index, fraction of IF from journal-self citation, proportion and magnitude of published citable articles, and total citation counts. High-IF and -Eigenfactor journals were considered those within the top-quartile of that metric each respective year.
Results: High-IF and -Eigenfactor otolaryngology journals displayed higher 5-year IFs, immediacy indexes, and IF without self-citation ( < .05 for all years) including total citations counts and citable articles when ranked by Eigenfactor ( < .05 for all years). Otolaryngology IF correlated with 5-year IF and immediacy index within the same year ( < .05 for all years) and from previous years ( < .05 for all years; < .05 for 2017-2018; > .05 for 2009-2016). Eigenfactor correlated with 5-year IF, total citation counts, and citable articles within the same year ( < .05 for all years) and previous years ( < .05 for 2013-2018). Multilinear regression revealed that 5-year IF ( < .05 for 2009-2018) and immediacy index from the prior 2 years ( < .05 for 2017-2018; > .05 for 2009-2016) predicted 2019 IF. Similarly, 5-year IF, total citation counts, and citable articles ( < .05 for 2013-2018) predicted 2019 Eigenfactor score.
Conclusion: Sustained publication of impactful articles is the dominant driver of high IF and Eigenfactor score. Eigenfactor score reflects a unique evaluation of otolaryngology journals; ranking otolaryngology journals by their Eigenfactor scores significantly alters journal ranking compared to ranking by IF.
Level Of Evidence: NA.

Background: Despite the global acceptance of the impact factor (IF) by researchers and academic institutions as one, criticism has been voiced regarding its effectiveness in evaluating the unbiased impact of a journal. To overcome the limitations and drawbacks of the IF that were presented by the scientific community, they introduced several other citation-based bibliometric indices.
Methods: All plastic and reconstructive surgery journals were analyzed, and bibliometric indices were extracted from the relevant source.

Background Bibliometrics refer to documents and citation-based measures that measure different aspects of performance of a journal, including impact, output and prestige. Objective The aim of this study was to collect bibliometric data of various Indian dermatology journals as well as Indian journals from other disciplines, in order to compare relative performances. Methods Journal metrics pertaining to various Indian journals, both from dermatology [Indian Journal of Dermatology, Venereology and Leprology (IJDVL), Indian Journal of Dermatology (IJD), Indian Dermatology Online Journal, Indian Journal of Pediatric Dermatology and International Journal of Trichology] and other disciplines [Indian Journal of Medical Research (IJMR), Indian Journal of Pediatrics (IJP), Indian Journal of Ophthalmology and Indian Journal of Pharmacology] were sought.
