What is EBP? Please see materials provided by your Professors.
I just wanted to mention the Heirarchy of Evidence Pyramid. Over the years some of the heirarchy has been revised. It would be prudent to search what is the hidhest evidence in EBP research. It still is Meta-analysis.

Brief definition of Meta Analysis:
Definition
A subset of systematic reviews; a method for systematically combining pertinent qualitative and quantitative study data from several selected studies to develop a single conclusion that has greater statistical power. This conclusion is statistically stronger than the analysis of any single study, due to increased numbers of subjects, greater diversity among subjects, or accumulated effects and results.
