Evidence-based practice "requires the integration of the best research evidence with our clinical expertise and our patient's unique values and circumstances." 1

Filtered information, in this context, is pre-appraised evidence.
To get filtered or “secondary” information, evidence from our primary literature is synthesized and evaluated. Those processes of evaluation, synthesizing data, and synopses take time and a lot work.
Filtered literature will often provide a more definitive answer than individual research reports.
Unfiltered information includes original research studies that have not yet been synthesized or aggregated. As such, they can be more difficult to read, interpret, and apply to practice.
Unfiltered does NOT mean that the research has not been peer-reviewed. This term refers to study design, not quality.
