Introduction Original research in peer-reviewed journals allows the re- viewanddisseminationofnewinformation.eincreasing complexity of research has resulted in increased collabo- ration among researchers (same institution or geographic region, or different countries) to obtain appropriate ex- pertise [1–3]. Collaboration is easier with the advances in technology [3]. Studies have suggested that international collaborations expand the dissemination of information, increasing readership and citations [1, 4]. Increasing collaboration may also be due to the “publish or perish” paradigm[5–9],aspublicationproductionisimportantatall career stages [9–11]. Medicine has traditionally been a field dominated by men,althoughwomenhavemadesignificantgains;in2018- 2019, women represented 49.5% of US medical school matriculates [12]. Due to a few senior-level women in ac- ademic medicine, it is important to examine publication trends relative to gender. In the USA, there has been no meaningful change in orthopedic surgery residents from 10.9% in 2006 to 14.4% in 2015 [13]. is minimal change Hindawi Scientifica Volume 2020, Article ID 5019607, 11 pages https://doi.org/10.1155/2020/5019607
