Scientific collaboration between researchers is one of the most important aspects in the evolution of science helping promote the quality of the studies that are carried out. In turn, it determines an increase in citations when research results are published in scholarly journals. It is interesting to explore the dynamics of scientific collaboration networks regarding co-authorship of scientific articles published in Medwave from January 2014 to September of 2017 and indexed in PubMed/MEDLINE. The largest collaboration networks occurred among authors Rada G, Corsi O and Peña J; and, at universities and healthcare centers level, in the Faculty of Medicine belonging to the Pontificia Universidad Católica de Chile located in Santiago, Chile.
