Thank you, Dr. Ludwin.
We need to move on to the next round. I'll take the Conservative round.
Thank you once again, everyone, for being here. It gives me particular pleasure to see Dr. McDonald. I represent the riding of Barrie, Ontario, and we take great pride in Barrie in having such a renowned vascular surgeon in our community.
I want to give you an opportunity to expand a little bit on some of the comments you made. I think it would be helpful if we gave you an opportunity to play devil's advocate. You can reference some of the concerns that have been raised.
I heard last week from a witness that to have an accurate sample size to make sure that this is a safe procedure you would have to have a sample size of 1,500. To have confidence in the safety of this procedure, what do you think would be a fair sample size?
