Conflict of Interest

To meet the responsibility to the public to provide clear and unbiased scientific information, all authors must disclose any association that poses a conflict of interest in connection with the manuscript. Authors must indicate any affiliations, funding sources, or financial holdings that might raise questions about possible causes of bias. This information will not be revealed to the reviewers and will not influence the decision concerning the acceptance of the manuscript. After the article is accepted for publication the Editor will discuss with the authors the manner in which the information concerning the financial sources should be provided to the readers. Reviewers and editors are also required to report any conflict of interest in case of recent collaborations with the author (co-authored a paper or worked together on a grant with the author within the past 24 months). Other examples of possible conflicts include a close personal friendship, past or present association as thesis advisor or thesis student, or a family relationship. Additionally, in case of articles presenting drugs or medical equipment, reviewers and editors should disclose to the Editor-in-Chief any financial relations with the corporations manufacturing described drugs and/or equipment.
