The Vancouver Style is the preferred referencing style for most Faculty of Medicine, Dentistry and Health Sciences courses. It is a numerical system.
This UWA guide to Vancouver is based on Citing medicine: the NLM style guide for authors, editors & publishers and AMA manual of style: a guide for authors and editors
The in-text citation:
A superscript number is inserted in your text at the point where you refer to (cite) your source of information. A consecutive number is allocated to each source as it is referred to for the first time. See the example text. This number becomes the unique identifier of that source and is reused each time that particular reference is cited in the text.
Use superscript numerals outside periods and commas, inside colons and semicolons. When more than 2 references are cited at a given place in the manuscript, use hyphens to join the first and last numbers of a closed series; use commas without space to separate other parts of a multiple citation.
The reference list:
References are listed numerically at the end of the body of work. Agreed abbreviations for journal titles must be used and can be searched for from the National Library of Medicine's (US) PubMed website within their NLM catalog: Journals referenced in the NCBI database.
If using the Endnote Referencing software you can install the Medicine Journal Terms List, which will includes over 16,000 Journal abbreviations.
