Is there anything else you want to add?
Don't be shy about bringing up something important that the interviewer didn't ask you. If you've forgotten to speak about something or a topic never came up during the conversation, now is the time to say so. Use this question to bring up a strong point or two that weren't discussed. The last impression you leave is often the strongest. If you think you've already left a strong impression, then you don't have to say anything. But if you think you need to reemphasize an important point, this is the time to make a final statement.
