When I'm looking through CVs I don't really care about the results you got from your research - They're only of any real use to the client you were working for at that time. The content of your past project is largely irrelevant to what you might be doing when you work with me.
Each job (especially in agency work) is different and requires a slightly different approach so the results you got for testing one piece of software may not be relevant for another, similar piece of software due to market forces, UI trends, political climate, business requirements, target audiences, etc.
What I am interested in are your analytical thinking skills and your experience with different methodologies.
As long as you can communicate how you gathered your data, how valuable/useful it was, and how you went about drawing conclusions from it then you should be fine.
Show me that you understand what to test, show me that you understand how to test, show me that you understand the value of test results in context, and show that you know how to use the results to infer creative direction and requirements. That's what I want to see.
