KJAN follows the recommendations for authorship set out by the ICMJE Authorship guidelines (http://www.icmje.org/icmje-recommendations.pdf). Authorship is attributed only to individuals who have directly participated and made significant contributions to the creation of the manuscript. Authorship should be based upon all four of the following criteria: 1) substantial contribution to the concept or design of the work, or the acquisition or analysis and interpretation of data; 2) drafting the work or revising it critically for important intellectual content; 3) final approval of the version submitted for publication; 4) accountability for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. All other contributors not listed as authors should be mentioned in the acknowledgements section.

If a manuscript is based on a master's thesis or doctoral dissertation, the author must disclose that the manuscript is the product of his/her thesis or a dissertation for an academic degree. The first author must be the recipient of the academic degree from the work presented in the manuscript.

Any changes in authorship (addition, deletion or change in order of authorship) must be approved by the Editorial Board prior to the manuscript's acceptance for publication. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason(s) for the change in the author list; and (b) written confirmation (e-mail, letter) from all authors that they agree with any addition, removal, or rearrangement.
