Questions From Users of the Manual

Q: Are arabic numerals used for measures of time:  years, months, weeks?

A: I’m assuming you are asking about using numerals vs words.  The short answer is yes; we use arabic numerals for years, months, and weeks.  But if you should also be curious about the use of  arabic vs roman numerals, see section 19.7.5; and for specific nomenclature conventions, see chapter 15.

Q: Do you have a style for citing tweets?

A: Our blog addressed this query on August 23, 2011.  Please take a look at this archived entry.

Q: How do you handle the word continued when it’s used after a title of a table that runs over onto a second page?

A: We don’t address this specifically in the manual, but if you look at one of the longest tables in the manual (the big SI conversion table in chapter 18) you will see that we used “(cont).”  Since then, however, in our own publications, we have switched to spelling the word out (“continued”) to better serve international readers (who may not recognize cont as a “familiar” abbreviation).

Q: If there is a “compound” acronym/abbreviation defined first in a manuscript (eg, chronic myeloid leukemia in chronic phase [CML-CP]) and, later in the same manuscript, just CML is required, should CML be redefined or did the first definition cover it?

A: Good question.  AMA Manual of Style authors agree that there is no need to expand a component of an already introduced compound abbreviation.  For instance, after introducing ST-elevation myocardial infarction (STEMI), there is no need to expand MI.  In your example, there is no need to treat CML as a new abbreviation.—Cheryl Iverson, MA
