Filtered and unfiltered resources are differentiated by the level of evaluation the resource has undergone.

Filtered resources have been evaluated for their quality, and often contain recommendations for practice. Examples include:

  • systematic reviews

  • meta-analyses

  • critically-appraised topics

  • critically-appraised individual articles


Unfiltered resources are primary or original research studies. Examples include:

  • randomized-controlled trails

  • cohort studies

  • case studies

If you are taking NURS 6052: Essentials of Evidence-Based Practice, you may want to refer to the NURS 6052 Week 2 Assignment Guide.
