I’d say that unless you’ve got any strong feelings about a treatment you want or don’t want, I’d participate. …But there are, I think there are always occasions when the treatments are so dramatically different that some people will have an in-built priority. But I think the, the amount of work that goes into setting up a trial, unless, unless there is no clear evidence that one treatment is any better than any other, the trial won’t get ethical approval. And the conditions around registering a trial, getting ethical approval and funding and everything have so, improved so much over the last ten years, I wouldn’t have any qualms that what a clinician was doing was unethical, because I know the rigours that they have to go through to get approval and you can’t do a trial without approval, and all the protection that’s in, in-built in the systems now, when you’re running a clinical trial, that you have to give reports and, you know, show how people are doing.
