The reference style followed by JAMA and its related journals was 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) and the National Library of Medicine's recommendations found in Citing Medicine:The NLM Style Guide for Authors, Editors, and Publishers.
APA (American Psychological Association) Style originated in 1929, when a group of psychologists, anthropologists, and business managers convened and sought to establish a simple set of procedures, or style rules, that would codify the many components of scientific writing to increase the ease of reading comprehension.
As with other editorial styles, APA Style consists of rules or guidelines that a publisher observes to ensure clear and consistent presentation of written material. It concerns uniform use of such elements as selection of headings, tone, and length, punctuation and abbreviations, presentation of numbers and statistics, construction of tables and figures, citation of references, and many other elements that are a part of a manuscript.

MLA (Modern Language Association) style for documentation is widely used in the humanities, especially in writing on language and literature. MLA style features brief parenthetical citations in the text keyed to an alphabetical list of works cited that appears at the end of the work. (Source Official MLA website)
