I have less than two minutes left, but I appreciate the fulsome explanation.
I want to focus on the U.S. and the way the recommendations are now in the U.S. preventive task force versus Canada.
You do acknowledge that we have included observational studies in the Canadian guidelines for the first time, but also that they are weighted differently from clinical trials. There's almost a time consideration because clinical trials, almost by definition, are older. The RCT has always been the gold standard of trials.
Do you see there is a process that is happening differently in the U.S. versus Canada? Should we be looking at processes that are potentially different, to emulate the U.S.? I'd also note that the U.K. has not changed from 50. As far as I know, the U.S. is perhaps one of the first to include the 40.
