General Rules for Article Type (optional) for Journal Articles Vancouver Style

An article type alerts the user that the reference is to an abstract of an article or a letter to the editor, not a full article. Content designator is another phrase for this.

Place [abstract] or [letter] after the article title.

Other article types are also available though used less often, such as book review, editorial, or interview.

Follow the bracketed article type with a period placed outside the closing bracket.
