Competing interests

Authors must notify the editors of any conflicts of interest with other people or organizations (associated with employment, sources of funding, personal financial interests, relationships, membership of relevant organisations, etc.). All potential conflicts of interest must be disclosed at the earliest possible stage.

Reviewers are asked to declare any potential competing interests related to the research (of financial, non-financial, professional or personal nature). Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships and/or connections with any of the authors, or their institutions. After manuscripts are assigned for review, referees are asked to inform the Editor of any conflicts of interest that may exist.
