The most easily identifiable conflict of interest are economic relationships, such as direct employment, consulting fees, company ownership, honoraria, patent authorship, or conference fees. However, there may also be conflict of interest arising from friendship, intellectual rivalry, academic competition, or beliefs.

When submitting an article for publication, all authors are responsible for declaring financial or personal relationships with any public or private organizations that could (intentionally) influence the results of their work. Likewise, authors must declare any non-financial relationships that may cause a conflict of interest in their manuscript (personal, academic, ideological, intellectual, political, or religious).

Conflict of interest, both financial and non-financial, must be disclosed at the time of article submission in order to clearly identify them and prevent authors with potential conflict of interest from being published.
A note "Conflict of interest" will be published at the end of the article. In case of its absence, the note will say "None".
