Thank you both for coming here. It's great to have you provide us with information that will assist us in our study.
Dr. Richardson, I'm going to go to you first, because your numbers are still fresh in my head and I don't want to forget them. I'll go to Dr. Pedlar afterwards, if you'll bear with me.
Doctor, you said that about 40% to 60% will recover. You've mirrored that same finding with your studies at Parkwood. Can you explain that population base, 40% to 60% of how many, or 40% to 60% of what type? Can you expand on that for me, please?
