Please cite references with Arabic numbers in squared parentheses and list them by the order in which they appear in the text (not in alphabetical order). References should be numbered consecutively in order of their appearance in the text and listed in numerical order. For references to journal articles, include the first 6 authors, followed by "et al" if there are more than 6 authors. The author names are followed by the title (with only the first word capitalized), the abbreviated name of the journal, the year, volume number (without issue number), and page range. Cite the references in the text by the appropriate number e.g. , [2, 3], [4-6], [7, 8-10] and the numbers should be within square brackets. Avoid using abstracts as references. Nothing should be italicized. Journal titles should be abbreviated according to the Index Medicus.
For chapters of books that have an editor(s) and individually authored chapters, include the names of the chapter authors, followed by the chapter title, the book editors, the book title, the city of publication, publisher name, year of publication, and chapter page range.
The list of references should only include works that are cited in the text and that have been published or accepted for publication ("in press"). Personal communications or unpublished data cannot be included in the reference list, but they should be mentioned in the text in parentheses including a date. Permission must be submitted when citing a personal communication. A paper published online but not (yet) in print can be cited using the Digital Object Identifier (DOI).
References with correct punctuation should be styled as follows:
