How to format your references using the Trials citation style

This is a short guide how to format citations and the bibliography in a manuscript for Trials. 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	Find the style here: output styles overview
Mendeley, Zotero, Papers, and others	The style is either built in or you can download a CSL file that is supported by most reference managers.
BibTeX	BibTeX styles 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

1. Gitler AD. Neuroscience. Another reason to exercise. Science. 2011;334:606–7.

A journal article with 2 authors

1. Singer AL, Koretzky GA. Control of T cell function by positive and negative regulators. Science. 2002;296:1639–40.

A journal article with 3 authors

1. Tagliabue G, Eghlidi H, Poulikakos D. Rapid-response low infrared emission broadband ultrathin plasmonic light absorber. Sci Rep. 2014;4:7181.

A journal article with 7 or more authors

1. Zhang J, Xie K, Wei H, Qin Q, Qi W, Yang L, et al. In situ formation of oxygen vacancy in perovskite Sr(0.95)Ti(0.8)Nb(0.1)M(0.1)O3 (M = Mn, Cr) toward efficient carbon dioxide electrolysis. Sci Rep. 2014;4:7082.

Books and book chapters

Here are examples of references for authored and edited books as well as book chapters.

An authored book

Blog post

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".

Government report

1. Government Accountability Office. Ready Reserve Force: Ship Readiness Has Improved, but Other Concerns Remain. Washington, DC: U.S. Government Printing Office; 1994 Nov. Report No.: NSIAD-95-24.

New York Times article

1. Davey M, Vlasic B, Walsh MW. Detroit Ruling Lifts a Shield on Pensions. New York Times. 2013 Dec 3;A1.
