This is a short guide how to format citations and the bibliography in a manuscript for Clinical Investigation. For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

BibTeXBibTeX 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.

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
Government Accountability Office. Buy America Requirements: Federal Enforcement Questioned in Sacramento Mass Transit Procurement. U.S. Government Printing Office, Washington, DC.
