Questions From Users of the Manual

Q: A colleague and I both remember seeing in a style manual that an en dash should be used between 2 words of equal weight. However, we checked the AMA Manual of Style and saw that this was not a supported use of the en dash. Did this guideline appear in a former edition of the AMA Manual, or did we just pick this idea up from another source?

A: No, I don’t believe we have ever recommended an en dash between 2 words of equal weight. It is the hyphen that we recommend between 2 words of equal weight. See the middle of page 346 of the 10th edition, with the examples of “blue-gray eyes” and “blue-black lesions.” We recommend use of the en dash when the items on either side are not of equal weight (eg, one element consists of 2 words or a hyphenated word or a compound). There are examples at the bottom of page 352 and the top of page 353.

Q: Is it appropriate to abbreviate echocardiography as ECHO or echo in documents that describe the use of echocardiography during the treatment of various types of cancer?

A: We would be unlikely to abbreviate echocardiography (or any related term, such as echocardiogram) to ECHO or echo. We would spell this term out. Only in cases in which there are serious space constraints would we consider abbreviating this term (eg, in a large table), and then we would recommend expanding the abbreviation in a table footnote.

Q: Do you use Web site or website? Traditionally it has always been “Web site,” but in the past few years I have noticed a change to the more informal “website” in many publications. What is your recommendation?

A: On the home page of the AMA Manual, in the navigation bar, there’s a listing for “Updates.” If you take a look there, you’ll see that a relatively recent update (January 18, 2012) indicates that, as of that date, we began to prefer website to Web site.  Check “Updates” periodically to see if there are other, newer updates on material in the manual.

Q: I have a style question I cannot find addressed in your manual. On a manuscript I plan to submit to a journal, the corresponding author has moved since the manuscript was written and this author wants to indicate both her current and her former affiliation. Can you advise on how to phrase this information?

A: The answer to your question is in section 2.3.3 of the manual. See the relevant excerpt below:

The affiliation listed, including departmental affiliation if appropriate, should reflect the author’s institutional affiliation at the time the work was done. If the author has since moved, the current affiliation also should be provided.

Author Affiliations: Department of Health Policy and Management, The Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland. Dr Lloyd is now with the Department of Emergency Medicine, St Luke’s Hospital, Milwaukee, Wisconsin.
