The list of references should only include works that are cited in the text and that have been published or accepted for publication. The accuracy of references is the responsibility of the author.
Number each reference consecutively in the order in which they are first mentioned in the text. Identify references in the text by Arabic numerals in superscript. If more than one reference, separate them by a comma (example: 3,4) or a dash if a sequence (example 5-7). References should be formatted according to the recommendations of the International Committee of Medical Journal Editors (http://www.icmje.org/recommendations/browse/manuscript-preparation/preparing-for-submission.html#g). Abbreviate the names of journals in accordance with MedLine. List the names of the first six authors in reference-list entries before adding ‘et al.’
