Journal policies

Ethics and transparency policies

General principles

RBE follows the guidelines of ethics and transparency established in the document: Principles of Transparency and Best Practice in Scholarly Publishing, published by the Committee on Publication Ethics (COPE), by the Directory of open Access Journals (DOAJ), by the Open Access Scholarly Publishers Association (OASPA) and by the World Association of Medical Editors (WAME). The full document is available at: https://doi.org/10.24318/cope.2019.1.12.

Approval by the Ethics Committee in Research (CEP)

All papers submitted to the RBE must have followed the recommendations of ethics in research of Declaration of Helsinki and the standards contained in the Resolutions No. 466/2012 and 510/2016 from the Brazilian Health Office (CNS, acronym in Portuguese). The approval by an Ethics Committee in Research (CEP, acronym in Portuguese) is not required for studies that analyze added data and data without people’s identification, such as those available in public domain databases. No instance is above the CEP to analyze the nature of investigation proposals, following the orientation of the Brazilian Commission of Ethics in Research, CNS, Brazilian Department of Health (CONEP/CNS/MS). The CEP that approves the investigation should be registered at the CONEP.

Submission of the CEP protocol copy is mandatory at the submission.

Clinical trials

The RBE supports the policies from the World Health Organization (WHO) and International Committee of Medical Journal Editors (ICMJE) for registration of clinical trials. Thus, it recognizes the importance of these initiatives for international registration and disclosure of open-access information. Therefore, only articles of clinical trials that have received an identification number in one of the clinical trials validated for the criteria established by the WHO and ICMJE, whose addresses are available at the ICMJE website, are accepted for publication. The identification/approval number should be registered in the title page.

The entities that register clinical trials according to ICMJE criteria are:

  • Australian New Zealand Clinical Trials Registry (ANZCTR)
  • ClinicalTrials.gov
  • International Standard Randomised Controlled Trial Number (ISRCTN)
  • Nederlands Trial Register (NTR)
  • UMIN Clinical Trials Registry (UMIN-CTR)
  • WHO International Clinical Trials Registry Platform (ICTRP)

Authorship

For definition of article authorship, the RBE follows the Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals elaborated by the International Committee of Medical Journal Editors (ICMJE). The authors should follow the guidelines available at http://www.icmje.org/

Research misconduct

In its protocols, RBE incorporates strict guidelines to prevent and identify possible research misconduct. In case any sign of misconduct is identified in a study submitted to the journal, the Editors-in-chief follow COPE’s guidelines to handle the situation. 

Data sharing

RBE encourages authors to make the raw data of their studies publicly available, as well as the routines used in data analyses. In the case of intervention studies, the data must be freely available, or at request, always in anonymity.

Policy of the peer review process

The peer review process is a vital stage of the article’s editorial process, so RBE handles it carefully. At the same time, the journal understands that agility, in an editorial process, is extremely important both for the authors and the scientific community. Therefore, RBE always aims at providing analyses with ethics, maximum scientific rigor and agility. In that sense, the following stages are determined:

  • Merit analysis by the Editors-in-chief: all of the received manuscripts are analyzed by the Editors-in-chief, who assess the (a) adequacy of the study to the journal’s scope, (b) the contribution it provides to the advancement of knowledge, (c), its originality, (d) the methodological rigor with which the study was conducted, (e) the adherence of the conclusions to the presented results.
  • Technical review of the manuscripts: the executive-secretariat of RBE evaluates if the formatting of the manuscripts selected by the Scientific Editors are in accordance with the technical instructions of the journal. If any incorrections are identified, the manuscript is sent back to the corresponding author, with the indication of the necessary adjustment. Only texts that meet all of the criteria described in the “Instructions to Authors” are sent to peer review. 
  • Peer Review: the manuscripts selected by the Editors-in-chief are sent to an Associated-Editor, who will be a researcher with solid and acknowledged background in the field addressed in the manuscript. This professional will indicate reviewers with notorious competence to analyze the study. Each manuscript will receive at least two opinions, which will be analyzed by the Associated Editor, who will then elaborate an opinion for the Editors-in-chief. The double blind peer review process os adopted by RBE, that is, reviewers and authors do not know the identity of the others.
  • Editorial Decision: Based on the opinions of the reviewers and the Associated Editor, the Editors-in-chief decide (1) on the refusal of the manuscript; (2) to give the authors a new chance after analyzing and responding to the received opinions; or (3) to approve the text with or without changes. In case of outcomes 2 and 3, the analysis of the new version of the manuscript can be carried out only by the editors, or the reviewed text can be sent again to ad hoc reviewers. More than one round of evaluation may be necessary for the manuscript, according to the editors’ opinions. If the authors do not observe the deadlines established by the journal, the submission can be archived.

All manuscripts are analyzed for the identification of plagiarism through appropriate softwares.

Regarding peer review, RBE reinforces the need for the strict observance of ethical requirements for reviewers, elaborated by the Committee on Publication Ethics, available at: https://publicationethics.org/files/Ethical_Guidelines_For_Peer_Reviewers_2.pdf

Gender Equity

Editors and reviewers of Revista Brasileira de Epidemiologia, along with the authors who publish in the journal, must always comply with the guidelines regarding Sex and Gender Equity in Research (SAGER). The SAGER guidelines include a set of orientations that guide the report of information on sex and gender in the study design, the data analysis and the result and interpretation of findings, as described in English at https://www.equator-network.org/reporting-guidelines/sager-guidelines/.

Besides, RBE observes the gender equity policy in the composition of its body of editors and reviewers.
