What is included in the CINAHL Evidence-Based Practice limiter?

If you use the CINAHL Evidence-Based Practice Limiter, do you wonder what is it really limiting? This is EBSCO's explanation:

Evidence-Based Practice is a value that can be found in the Special Interest field of some CINAHL records. This value is associated with a record when an article is about the application of Evidence-Based medicine.
Evidence-based medicine is a medical movement based upon the application of the scientific method to medical practice, including long-established existing medical traditions not yet subjected to adequate scientific scrutiny. According to the Centre for Evidence-Based Medicine, "Evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients."

When applied, the Evidence-Based Practice limiter searches the Special Interest field for the value "Evidence-Based Practice." Applying this limiter allows you to limit results to:
• Articles from evidence-based practice journals
• Articles about evidence-based practice
• Research articles (including systematic reviews, clinical trials, meta analyses, etc.)
• Commentaries on research studies (applying practice to research)
It does not limit searchers to articles that report evidence-based conclusions.
