3 ETHICAL PRINCIPLES AND REGISTRATION OF CLINICAL TRIALS
3.1 Experimental procedures in humans and animals
JAOS reassures the principles incorporated in the Helsinky Declaration and insists that all research involving human beings, in the event of publication in this journal, be conducted in conformity with such principles and others specified in the respective ethics committees of authors’ institution. In the case of experiments with animals, the same ethical principles must also be followed. When surgical procedures in animals were used, the authors should present, in the Methodology section, evidence that the dose of a proper substance was adequate to produce anesthesia during the entire surgical procedure. All experiments conducted in human or animals must accompany a description, in the Methodology section, that the study was approved by the respective Ethics Committee of authors’ affiliation and provide the number of the protocol approval.
3.1.1 Papers presenting experimentalstudies in human volunteers or in animals must contain the Ethical Committee approval of the reports as mandatory supplementary file.
3.1.2 Papers describing studies in animals must be submitted with the ARRIVE Checklist as mandatory supplementary file. The ARRIVE Checklist is available at
3.1.3 Ethics Committee certificate written in different languages from English, Spanish and Portuguese must be full translated into English.
3.2 Clinical Trial Registration
JAOS supports the policies of the World
Health Organization (WHO) and the International Committee of Medical
Journal Editors (ICMJE) for the registration of clinical trials. The
journal recognizes the importance of such initiatives for the registration
and international publication of clinical studies with an open access.
Therefore, JAOS will publish only those
clinical trials that have previously received an identification number validated by the criteria established by the WHO and ICMJE.
The WHO defines clinical trials as "any research study that prospectively
assigns human participants or groups of humans to one or more health-related
interventions to evaluate the effects on health outcomes. Interventions
include but are not restricted to drugs, cells and other biological
products, surgical procedures, radiologic procedures, devices, behavioral
treatments, process-of-care changes, preventive care, etc".
3.2.1 Manuscripts presenting clinical trials in human volunteers
must be submitted with the following mandatory supplementary files:
3.2.2 Survey-based studies must be submitted following the same instructions of the item above.
3.3 Systematic Reviews
Systematic Reviews SHOULD ONLY BE SUBMITTED AT THE INVITATION OF JAOS. And even in these cases, JAOS will only receive Systematic Reviews of any kind (Traditional, Overviews, Umbrella Reviews and Scoping Reviews) if they meet 2 mandatory requirements:
- The prior publication of the research protocol of the Systematic Review in a scientific journal or the proof of the prior registration number of the Systematic Review protocol in a specific online platform for this purpose. Submissions with a registration date from after the date of submission of the article to JAOS will not be accepted. For registering the Systematic Review, the following platforms are suggested:
- PROSPERO (https://www.crd.york.ac.uk/prospero) International Prospective Register of Systematic Reviews)
- Open Science Framework (https://osf.io)
- Joanna Briggs Institute (https://joannabriggs.org/)
- Cochrane Library (https://www.cochranelibrary.com/)
- Duly filled PRISMA Checklist (http://www.prisma-statement.org/), including all applicable extensions for particular cases.
3.4 The Editor-in-Chief and the Editorial Board reserve the right to
refuse manuscripts that show no clear evidence that the methods used
were not appropriate for experiments in humans or animals.
4 ANY FURTHER QUERIES SHALL BE SOLVED BY THE Editor-in-Chief AND EDITORIAL BOARD
