Vancouver uses numbers in the text and a references list.
In-text citation
At every point in the text where a particular work is referred to by quoting or paraphrasing, include the number which identifies the reference used, in brackets. References are numbered consecutively in the order in which they are first cited in the text.
References list
References are presented in numerical order by the order in which they appear in the document.
You should only include sources that you have referenced in your work.
If you are asked to include a bibliography (in addition to, or in place of, a references list) you can include further items that were read that informed your research and thinking for the assignment, in addition to those that you directly referenced.
