«Each author should have participated sufficiently in the work to take public responsibility for the content. Authorship credit should be based on only substantial contributions to (a) conception and design, or analysis and interpretation of data; and to (b) drafting the article or revising it critically for important intellectual content; and on (c) final approval of the version to be published. Conditions (a), (b), and (c) must all be met.»
