Study Characteristics Related to Citation Rates in Hip & Pelvis: An Analysis of Articles Published between 2009 and 2019 / 대한고관절학회지

ABSTRACT

Purpose@#We classified the articles published in the journal Hip & Pelvis and analyzed the relationship between study characteristics and citation rates. @*Materials and Methods@#All articles published in Hip & Pelvis from 2009 to 2019 were included. We classified the articles according to the type, language, listing in PubMed Central (PMC), treatment modality, material, design, anatomical focus, number of authors, and number of cases. We analyzed the citation rate according to this classification, with yearly citation rate reflecting the exposure period until March 2020. @*Results@#The yearly citation rate increased significantly after the language of the journal was changed from Korean to English in June 2014 (mean=0.96 vs. 1.63, P<0.05), and again after the journal was listed in PMC in March 2016 (mean=1.05 vs. 1.92, P<0.05). The yearly citation rates of review articles was highest, followed by those of editorials, original articles, and case reports (in this order). Among original articles, trauma-related articles had higher yearly citation rates than non-trauma-related articles (mean=1.00 vs. 0.68, P=0.034). Among clinical articles, studies focusing on the pelvis had higher yearly citation rates than studies on the hip or femur (mean=1.85 vs. 0.71 vs. 0.91, P=0.003). @*Conclusion@#The yearly citation rate of articles increased significantly after the language of Hip & Pelvis was changed to English and after the journal was listed in PMC. The mean yearly citation rate of articles focusing on the pelvis was significantly higher than that of articles focusing on the hip or femur.
