DER Minor Medical Descriptors

 

kidney-failure in der

kidney failure in der

 

The DER field contains medical index terms, taken from the controlled vocabulary called EMTREE, that describe the secondary topics of the document. The DER field enables you to search for minor medical descriptors only. The Subjects (SU) field enables you to search in the Minor Medical Descriptors (DER) and Major Medical Descriptors (DEM) fields simultaneously.

 

For most precise results, search for descriptors as hyphenated, "bound" phrases. For example, kidney-failure in der retrieves only occurrences of "kidney-failure" in the DER field. Hyphenate single-word descriptors, such as dyslexia- in der, to limit the search to the single-word descriptor term.

 

Do not hyphenate your search term to retrieve occurrences of your term as well as variations of your term. For example, kidney failure in der retrieves occurrences of "kidney-failure," "kidney-failure-complication," "chronic-kidney failure-etiology," etc. in the DER field.

 

Refine your search by adding a link term, such as "diagnosis," to a descriptor term: kidney-failure-diagnosis
