that equal

that equal selects attributes that have a specified value from group attribute or other set of attribute.

A typical use of this function is to extract, from a group attribute or other set of attributes, those attributes in a case that have a particular value. For example, suppose that the attributes Aorta0002, Aorta0003, Aorta0004 and Aorta0005 are all in the group AbnormalAortaObservations. Then given the following case:

Ao0002          T
Ao0003          F
Ao0004
Ao0005          T

we could add the variable comment

The following abnormal aorta findings are noted: {AbnormalAortaObservations that equal "T"}.

with a condition such as

AbnormalAortaObservations that equal "T" is not empty

The comment would evaluate as “The following abnormal aorta findings are noted: Ao0002 and Ao0005.”

Note that the text matching performed by this function is not case sensitive. Also, the matching attempts to match values that are equal as numbers.
