Below is the EBM Pyramid. This pyramid depicts how the quality of evidence differs by resource type. To learn what databases are available for the various resource types, please see the database listings below the EBM Pyramid. For most courses, you will use information categorized as Unfiltered Information as you are doing your literature reviews.
**Note, scroll down after the pyramid to see lists of suggested resources that index information from specific levels of the pyramid.

Authors of critically-appraised topics evaluate and synthesize multiple research studies.
Authors of critically-appraised individual articles evaluate and synopsize individual research studies.
