The ethical criteria of research must be respected. In this sense, the authors of original articles, quick communications, and systematic reviews/meta-analyses must specify, in METHODS, that the research was concluded in accordance with the standards required by the Helsinki Declaration and approved by the ethics committee recognized by the National Research Ethics Commission (Comissão Nacional de Ética em Pesquisa - Conep), linked to the National Health Council (Conselho Nacional de Saúde - CNS),  citing the code of that approval.
