General style notes
About Vancouver
Vancouver is a numbered referencing style often used in medicine and health sciences. It was developed by the American Medical Association for use in the Journal of the American Medical Association (JAMA).
There are two elements:
- Citations in the text, indicated by a number.
- A reference list at the end of the document providing full details of the in-text citations, keeping the original numbering.
There are other variations of this style that may be referred to as the Vancouver style.
Style notes
Here are some notes on the Vancouver style to get you started. For more specific instructions check the style notes on each reference type.

It is common for element to be missing from web references. Only include the details you can see on the resource.
Artificial Intelligence Software (eg ChatGPT)
There are no specific guidelines for citing ChatGPT or other generative AI in the International Committee of Medical Journal Editors, which is used as the basis for Vancouver style. In the interim, references from AI chat generators are being treated as personal communications. Use this resource to guide you on how to appropriately acknowledge the use of AI tools and technologies in your assessments.
Check with your lecturers and tutors whether artificial intelligence (AI) text generators are permitted in your assessment tasks. For more information, see the Academic Integrity Statement on Artificial Intelligence Tools and Technologies.
