“…Level IV studies constitute landmark case series and literature review articles with high numbers of citations, which have been observed in multiple other specialties including orthopedics and plastics surgery. 26,27,30 Amiri et al 25 found that more than 70% of the top 50 most-cited articles in spinal surgery were of level IV evidence.…”

Background: The purposes of this study were to analyze the trends in Oxford level of evidence (LOE), LOE of most-cited articles, and association between LOE and journal impact factor (IF) and SCImago Journal Rank (SJR) over a 10-year period (2009-2018) in 3 prominent hand surgery journals, specifically HAND, Journal of Hand Surgery ( American Volume) ( JHS), and Journal of Hand Surgery ( European Volume) ( JHSE). Methods: All articles published from 2009 to 2018 in HAND, JHS, and JHSE were reviewed for assigned or available LOE. Data were pooled and analyzed for trends in LOE; relationship among IF, SJR, and LOE; and citation density. Results: A total of 3921 total publications were tabulated from 2009 to 2018, with the majority of studies being level V (1700, 43%) and fewer studies being level I (146, 4%). Over the 10-year study period, there was no significant change in frequency of level I studies for any journal. HAND trended significantly toward higher LOE, JHS trended toward higher LOE, and JHSE trended toward decreased LOE without significance. Among all journals, the annual number of articles and the average LOE were independent significant predictors of IF and SJR. Statistically significant correlations were found between citation density and LOE for JHS and HAND. Conclusions: Higher quality evidence is becoming more prevalent in the hand surgery literature over the past 10 years. Annual articles, average LOE, and level I and II and level IV articles were significant predictors of increasing IF and SJR.

“…While optimizing the IF has positive effects such as having journals compete and helping to rank researchers, it has its drawbacks, since some journals focus narrowly on increasing their IF. While some question whether the IF is still a useful concept, it continues to be used to compare journals to each other [5][6][7][8][9].…”
