@jumbanho right, I said RCTs are indirect, and you disagreed while describing how indirect they are :)

Yes, you laid out nicely that RCTs are indirect. If you're continuing to disagree, I don't know why.

At this point I guess you just don't realize that the study did what you were asking for, and I don't know whether that's because you don't understand the study or you don't know what you're asking for.

I'm not sure where your disconnect is there.
