How to format your references using the Gastrointestinal Intervention citation style

This is a short guide how to format citations and the bibliography in a manuscript for Gastrointestinal Intervention (GII). For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

Typically you don't format your citations and bibliography by hand. The easiest way is to use a reference manager:

Paperpile	The citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNote	Download the output style file
Mendeley, Zotero, Papers, and others	The style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeX	BibTeX syles are usually part of a LaTeX template. Check the instructions to authors if the publisher offers a LaTeX template for this journal.

Journal articles

Those examples are references to articles in scholarly journals and how they are supposed to appear in your bibliography.

Not all journals organize their published articles in volumes and issues, so these fields are optional. Some electronic journals do not provide a page range, but instead list an article identifier. In a case like this it's safe to use the article identifier instead of the page range.

A journal article with 1 author

Fisk D. The Urban Challenge. Science. 2012;336(6087):1396–7.

A journal article with 2 authors

Zanetti M., Mahadevan NR. Cancer. Immune surveillance from chromosomal chaos? Science. 2012;337(6102):1616–7.

A journal article with 3 authors

Takahashi T., Svoboda K., Malinow R. Experience strengthening transmission by driving AMPA receptors into synapses. Science. 2003;299(5612):1585–8.

A journal article with 7 or more authors

Shen Q., Zhang Q., Shi Y., Shi Q., Jiang Y., Gu Y., et al. Tet2 promotes pathogen infection-induced myelopoiesis through mRNA oxidation. Nature. 2018;554(7690):123–7.

Reports

This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".
