Changing trends in otorhinolaryngology publishing
The aim of this study is to compare the changes in impact factors and citation numbers of Open Access (OA) vs subscription-based (SB) journals between 1999 and 2016 and to explore the changing trends in ORL publishing. All data extracted from SCImago Journal and Country ranking (SJR) website have been used as input for statistical analysis. The chi-square test of independency was applied in order to understand whether the ratio of number of OA journals of ORL category have dramatically changed between years 1999 and 2016. Also, the years and impact factors of journals belonging to the OA and SB journals have been graphed separately and the changes of annual SJR ranks of both journal types have been compared using one-way Z-test. There was a statistical difference as the proportion of OA Journals were not equal to the proportion of SB Journals throughout the years 1999 and 2016, and it showed the tendency to increase greater compared to SB Journals (p < 0.01). Although the overall level of impact factors of SB journals was generally high, by comparing two regression models, it was obvious that the level of increase of the impact factors of OA journals were significantly higher (p < 0.01). When choosing where to publish, it is important to consider the journal’s visibility, cost of publication, IF or SJR of the journal and speed of publication as well as changing trends in medical publishing nourished by the Web of Science.
