For more detailed information about acronyms, see section 10.6 of the AMA Manual.
For more detailed information about abbreviations, see section 14 of the AMA Manual.
Acronyms, abbreviations, and initialisms are discouraged from use, except for well-known and accepted units of measurement and some well-recognized terms.
Do not capitalize the words from which an acronym or initialism is derived.
Exception: When the words that form the acronym or initialism are proper names, use capitals. See example: ,
For even more detailed information on the proper use of numerals, see section 19.2 of the AMA Manual.
Numerals (1, 2, 3, etc.) should be used in all writing, except when:
However, 24 hour or military time convention MAY also be used to convey precise timing when needed, such as when describing drug dosage regimens or a 24-hour experiment.
See 19.1.3 of the AMA Manual for further information.
EXAMPLE: April 2, 2010
EXAMPLE: 1600 km, not 1,600 km.
For more specific information on the correct use of units of measure, see 18.1 in the AMA Manual.
But: When a unit of measure follows a number that begins a sentence, it too must be written out, even if the same unit is abbreviated elsewhere in the same sentence. Rewording the sentence may be preferable (see 18.3, Units of Measure, Format, Style, and Punctuation).
Okay: Two milligrams of haloperidol was administered at 9 pm, followed by 1 mg at 3:30 am.
Better: At 9 pm, 2 mg of haloperidol was administered, followed at 3:30 am by 1 mg.
Do not include “personal communications” in the list of references. The following forms may be used in the text:
The author should give the date of the communication and indicate whether it was in oral or written (including email) form. Highest academic degrees should also be given. If the affiliation of the person would better establish the relevance and authority of the citation, it should be included (see the example above, where H. R. Smith is identified as the drug’s manufacturer).
For quoting material longer than 4 lines, use a block quote.
In this case the material should be set off in a block, ie, in reduced type and without the quotation marks. Paragraph indents are generally not used unless the quoted material is known to begin a paragraph. Space is often added both above and below these longer quotations.
It is important to keep in mind:
Raw food diets are extreme dietary regiments that have not been investigated
extensively. For those that have been investigated the benefits are still considered
controversial. There is also little information about the effect of consuming a raw
vegan diet on the immune system. Extra caution is suggested when studying vulnerable
populations and assessment of the nutritional adequacy of the diet is most reliably made
on a case-by-case basis.6
If the block quotation appears in a section to be set in reduced type, do not reduce the type size of the quoted material further.
If another quotation appears within a block quote, use double quotation marks around the contained quotation, rather than setting off in blocks, regardless of the length.
Use quotation marks to enclose a direct quotation of no more than 4 lines from textual material or speeches.
Brackets are used to indicate your own editorial changes or additions within a quotation.

Thompson stated, “Because of the patient’s preferences, surgery was absolutely contraindicated [italics added].”
