Conflict of Interest Policy

Conflicts of interest and funding sources

Public trust in the scientific process and the credibility of published articles depend in part on how transparently conflicts of interest are handled during the planning, implementation, writing, peer review, editing, and publication of scientific work.

A conflict of interest exists when professional judgment concerning a primary interest (such as patients’ welfare or the validity of research) may be influenced by a secondary interest (such as financial gain). 

Financial relationships are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the authors, and science itself. However, conflicts can occur for other reasons, such as personal relationships or rivalries, academic competition, and intellectual beliefs. Authors should avoid entering in to agreements with study sponsors, both for-profit and nonprofit, that interfere with authors’ access to all of the study’s data or that interfere with their ability to analyze and interpret the data and to prepare and publish manuscripts independently when and where they choose.

All participants in the peer-review and publication process - not only authors but also peer reviewers, editors, and editorial board members of journals - must consider their conflicts of interest when fulfilling their roles in the process of article review and publication and must disclose all relationships that could be viewed as potential conflicts of interest.

When authors submit a manuscript of any type or format they are responsible for disclosing all financial and personal relationships that might bias or be seen to bias their work.

The details of all sources of funding for the study must be stated, together with a description of their role in the study design and in the decision to submit the article for publication. The precision and accuracy of the contents, as well as the opinions expressed are the sole responsibility of the author.

All authors must complete and submit the ICMJE Form for Disclosure of Potential Conflicts of Interest available at: This information will be kept confidential during the manuscript review and will not influence the editorial decision but will be published if the article is accepted. If there are no conflicts of interest, the authors must state this fact.

This information should be provided under the section entitled “Declaration of Conflicts of Interest”, which should appear after the “Acknowledgements” section and before the “References” section. The absence of any conflict of interest must also be declared.


Editors, members of the editorial board and journal staff as authors

The PJP will consider original papers submitted by editors, members of the editorial board and journal staff, but these are not involved in editorial decisions about their own scholarly work.
After submission, an editorial assistant will verify if any member of the PJP team is an author, in which case, these members will be excluded from publication decisions. The PJP has 2 Editors-in-Chief and one of them (without authorship responsibility) will assign one editor that is unbiased, to coordinate and supervise the review process.
