Reference Models

Referencing Guidelines – Vancouver Style

Below are illustrative examples of references in the Vancouver format. For a complete list of examples for various types of documents, consult: Citing Medicine, 2nd edition. Additionally, a compilation of examples can be accessed through the page: Samples of Formatted References for Authors of Journal Articles.

General Guidelines

  • Formatting: References must be numbered consecutively in the order in which they first appear in the text. Spacing should be single, and alignment should be left-aligned.
  • Reference Limit: The maximum number is 30 references. For review articles, there is no limit on the number of references.
  • Source Selection: It is recommended to include current references that are directly related to the topic, avoiding an excessive number of references in a single citation.

Online References

  • Access Date: All references accessed online must include the access date in the format: [cited year month day].
  • DOI: For scientific articles, the Digital Object Identifier (DOI) must be added. If the DOI is unavailable, provide the access URL.
  • Availability: All links must be functioning properly. References with unavailable links are not valid.

Abbreviation of Journal Titles

Journal titles should be abbreviated according to their official pages. Abbreviations can also be checked in the following databases:

Bilingual or Multilingual Articles

  • For articles available in multiple languages, the English version should be used for the reference, maintaining the pagination and the corresponding DOI.

Other Information

  • Citations from guides, manuals, booklets, and similar materials will only be accepted if issued by official organizations, such as IBGE, WHO, Ministry of Health, INCA, among others.
  • References or citations from abstracts will not be accepted.
