The Vancouver referencing style is a numeric style used in the medical sciences.
Vancouver style is based on guidelines established by the International Committee of Medical Journal Editors (ICMJE). In this style:
References in the text, tables, and legends are sequentially numbered using numbers enclosed in parentheses. These numbers correspond to the full citations listed numerically in the reference list. Numbers in superscript format are also acceptable, depending on the specific requirements of individual journals or academic departments.
Journal titles in the Vancouver style are abbreviated according to National Library of Medicine abbreviations.
