Ultrasound Quarterly: September 2022 - Volume 38 - Issue 3 - p 202-207 doi: 10.1097/RUQ.0000000000000615 Buy SDC Metrics Abstract One of the most widely applied methods for evaluating a research paper's quality is the impact factor (IF). The term JUMPS was applied to the IF in an article published in PubMed in 2021, describing an increase of more than 40% of IF. In this study, we aimed to compare the growth rate of IF JUMPS in Radiology, Nuclear Medicine & Medical Imaging in the last 6 years. This retrospective study calculated the growth rate (JUMP) in IF from 2015 to 2020. We used the Friedman and Wilcoxon signed ranks tests to calculate the statistically significant difference in IF from 2015 to 2020 and the 2019 to 2020 difference. We classified JUMPS in negative growth rate, quartiles, and journals with >100%. Three journals had more than 100% IF growth rate during 2020 (Zeitschrift fur Medizinische Physik, Journal of the Belgian Society of Radiology, and Ultrasound Quarterly). A 76% to 100% growth rate was observed in another 4 journals (3.2%), and 8 journals (6.3%) depicted a 51% to 75% percentage of change. Repeated measures analyses showed a significant difference (P < 0.001). During the COVID-19 pandemic, several journals in the Radiology, Nuclear Medicine & Medical Imaging category increased their IF by 50%. Knowing the growing trends in this category might supplement the assessment of target journals for authors looking to submit their works. Copyright © 2022 Wolters Kluwer Health, Inc.
