We offer two types of searches, which can be used independently or combined.
"Search Study Metadata by Keyword" – searches study metadata using keyword to find studies. For example, you can search keyword “trial” in “Design”, “transfusion” in “overview” or "DNA" in “Biospecimen”. To find keywords in variables, search keywords in the “variable description”, “value set”, and “Data Element” fields.
"Search Data Element by Concept Category" - searches study variables organized by Concept, CORE CDE, or PRO Measures categories, then the sub-categories and data element, and returns study name. For example, to search for imaging data, select "Imaging", then "MRI", then "Heart". Note: Please fill out all the subsets of the filter boxes or the filter will be ignored.
