The editorial team undertakes to ensure that the selected reviewers are apt and able to judge the works without conflicts of interests with the authors. Reviewers are expected to declare any possible conflict of interest and to consider the study they are reviewing as a confidential document until it is published. Under no circumstances may they disseminate or use information, details, arguments or interpretations contained in the text subject to review for their own benefit or that of other individuals, nor for the purpose of favouring or harming third parties. In their reviews, reviewers are expected to point out relevant published work which has not been cited.
