Right, and I appreciate that. I understand, as you will understand, that.... I get it that we have observational evidence. The problem we have with observational evidence, compared with randomized controlled trials, is that, number one, the risk of bias is much higher. As well, the quality of evidence is much lower. You have those challenges when you're trying to do that. I agree with you about the aspect of looking at who wrote the paper and what biases they might have. They might be affiliated with some organization.
At any rate, I want to go on a little bit, if I can. I appreciate your comments on that.
