AMA vs Vancouver and Your Journal’s Citation Requirements

Is AMA the same as Vancouver?

The names overlap in some teaching resources. The University of Melbourne calls its guide AMA (Vancouver), links to the AMA Manual of Style, 11th edition, and illustrates superscripts. That label tells you how the university teaches the system. It cannot establish the detailed requirements of every medical journal.

ICMJE recommends numbering sources by first mention, uses parentheses in its general instructions, and directs authors to NLM reference standards. It also tells authors to consult their destination journal. PLOS Medicine’s square brackets and JAMA’s superscripts show why that final step matters.

Use the broad style name to find the relevant guidance, then resolve the details against the named manual or journal. When an assignment specifies an institutional guide, follow that guide and ask about any conflict with another source.

Identify the named manual and journal variant

Open the journal’s current instructions and locate its references section. JAMA names AMA style, requires journal abbreviations, and asks for issue numbers after volume numbers. For works with more than six authors, it specifies the first three followed by et al.

PLOS Medicine calls its reference system Vancouver and links to the ICMJE sample references. Its stated author rule retains the first six before et al. for a longer list. These are requirements from two particular submission guides. They do not create a rule that every Vancouver journal truncates names identically.

Check the submission stage before undertaking a large reformatting job. PLOS Medicine permits format-free initial and full submissions. Its detailed style requirements apply when authors are invited to revise for publication after a positive peer-review decision.

Compare the same source under specified instructions

Our shared source is the PLOS Medicine version of Page and colleagues’ PRISMA 2020 statement, published in 2021, volume 18, issue 3, article e1003583. Its DOI is 10.1371/journal.pmed.1003583. The publisher’s author list begins with Page, McKenzie, Bossuyt, Boutron, Hoffmann, and Mulrow, and continues beyond six names.

The examples apply the two guides’ stated body-marker and author-list rules. They are limited editorial comparisons, with the source identity kept fixed. The sentence identifies the paper for a formatting exercise and makes no claim about its findings.

Check numbering, names, and bibliographic details

The shared DOI stays the same whichever journal receives the manuscript. Changing style should not change which article you cite. Keep the full author list in your source record and let the selected output rule determine which names appear in the manuscript.

NLM’s sample-reference page shows a six-author truncation example while noting that NLM itself now lists all authors. It also presents optional variations, including omission of an issue number for some continuously paginated journals. An export or a sample therefore needs to be checked against the journal’s explicit requirements.

For each reference, verify the article title and journal abbreviation, then check its year, volume, and locator. The PRISMA source above uses e1003583 as an article identifier; it does not have a conventional page range to invent or shorten. Confirm that the DOI resolves to this version of the statement.

Read through the body in order and check each number against the list. Include table and figure citations according to the journal’s directions. A correct-looking bracket does not establish that a source supports the sentence beside it.

Save the target journal’s current requirements

Keep the instruction URL and the date you checked it with your manuscript. Record the manual or supplied style-file name, the citation marker, and the author cutoff. Add any explicit instructions about issue numbers and identifiers. This short note gives a coauthor a concrete reference when a formatting disagreement arises.

Before resubmitting elsewhere, reopen the new journal’s guide and compare it with that note. Test one long author list and one ordinary journal reference before changing the entire manuscript. Inspect the resulting document and its submission copy, especially after moving paragraphs or switching reference-manager styles.

Choose an AMA or Vancouver citation style for the actual destination

Choose the destination journal’s supplied style when available and compare its output with the current instructions. If the journal’s example conflicts with its written rule, ask its editorial office which to apply.

AMA Cite prepares AMA reference drafts from source details; it has no separate Vancouver engine and does not certify journal compliance. JAMA also cautions against using AI, language models, or chatbots to generate or format references. Check your journal’s tool policy before deciding how to prepare and verify a submission.
