You can also click Scope Note (in the 'Scope' column) for a definition of the subject heading.
Subheadings: Once you select a subject heading, you are given the option to select subheadings from a blue menu to the right of the list of subject headings. Selecting a subheading will restrict your results to those that focus on a specific aspect of your topic. For example, you might select the subject heading 'Diabetes Mellitus, Type 1' and then select the subheading 'Diagnosis/DI' to find articles that focus on the diagnosis of type 1 diabetes.
Once you have made your selections, select Search Database to the right of the screen.
The search will appear as a line in the Search History / Alerts section beneath the search boxes on the Advanced Search screen.
