The AMA Manual of Style: A Guide for Authors and Editors is a guide to the frequently-used reference type followed by JAMA and its related journals. The manual is available online and periodically updated to reflect emerging citation needs, such as preprints, data repositories, and various forms of multimedia.

Formatting in MEDLINE and PubMed is according to Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers.

Both the AMA and NLM style guides were developed from recommendations contained in the ICMJE Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals (formerly known as the Vancouver style).
