Vancouver style (also referred to as ICMJE and Uniform Requirements Style) is a citation style used heavily in the health and biomedical sciences. The Vancouver style uses the citation-sequence system, meaning that references at the end of your paper are numbered in the order in which they appear in your paper (like AMA style), rather than listed alphabetically by author (like APA style).
Another important characteristic of Vancouver style references is the use of journal title abbreviations rather than full titles. Journal title abbreviations are standardized and can be looked up in the resources below.
