Based on the ICJME recommendations "all those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors. Those who do not meet all four criteria should be acknowledged". Author's contribution should be stated in the declaration section. All authors should be accountable for all sections of the manuscript and declare that it is written originally and there is no data fabrication; data falsification includes deceptive manipulation of images and plagiarism.
Any change in authorship (i.e. order, addition, and deletion of authors) after initial submission must be approved by all authors via written confirmation, in line with COPE guidelines. It is the corresponding author’s responsibility to ensure that all authors confirm they agree with the proposed changes. If there is disagreement amongst the authors concerning authorship and a satisfactory agreement cannot be reached, the authors must contact their institution(s) for a resolution. It is not the journal editor’s responsibility to resolve authorship disputes. A change in authorship after publication of an article can only be amended via publication of an Erratum.
