): "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 0000 and 0000....There was a statistical difference as the proportion of OA Journals were not equal to the proportion of SB Journals throughout the years 0000 and 0000, and it showed the tendency to increase greater compared to SB Journals (p < 0.00). 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 < 0.00)."
