PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Numerator, not nominator is top of a fraction

Ebm Audit   (2012-09-27 11:20)  Private

The ankle brachial index is defined in the abstract by an invalid nomenclature despite being the center piece of the article. It is a fraction of arterial blood pressure values with a value representing the legs (ankle) on the top of the fraction and a value representing the arms (brachial) on the bottom of the fraction. In the English language, the numerator is the top and the denominator the bottom of the fraction. Reference:

A nominator is not a mathematical term. The verb nominate expresses, for example, to propose a person by name as a candidate or to appoint to an office. A nominator may be a person who enters a horse in a race. Reference:
