Are you going to be specific, or make the person you're replying to do all of the work? They told you what they thought was relevant. If you've reviewed one of the others and found it relevant, say which and why, and ask why they disagree.

The person I replied to had apparently already done that work. That's why I asked the question. I haven't made any judgements on which studies were relevant / irrelevant.
