Reasons and implications of retracted articles in Brazil/Razoes e implicacoes de artigos retratados no Brasil

Over the years, cases of retractions due to unintentional errors or research misconduct have been the subject of discussion, being indispensable to avoid the propagation of misleading information. To understand this matter in the Brazilian scenario, this study characterizes the retractions of authorship or co-authorship of Brazilian researchers between 2002 and 2019, their related consequences and impacts on scientific activity. With a data collection performed at the Retraction Watch database, we analyzed quantitative aspects of the reasons for retractions, stratification by areas of knowledge, the time between publication and retraction, the association of journals and impact factor, authors' recidivism, the institutional collaboration between Brazilian institutions and countries and funding sources. The results of the analysis of 162 retractions indicate the prevalence of plagiarism (12.2%), the incidence of retracted articles in the Bioscience area (28.1%), in journals with Impact Factors between 2 and 5 (38.0%), and with 2 to 4 authors (38.8%). The occurrences and recurrences of retractions due to misconduct have an impact not only the author's professional activity but science. Thus, this article emphasizes the importance of prompt retraction, as well as of the need to improve mechanisms to prevent these articles from being published from the start.
