One thing that is still open after Dr.PathRoch’s answer:

Was that from a primary source or from a summary of one?

Pushing back on lucas_SP_BR here. This treats a plausible mechanism as a demonstrated one. Plausible is where you start looking, not where you stop.

Right, and the exception is worth naming rather than left implied, because the exception is where people get into trouble.

Happy to go further on any of that.

Genuinely useful, thank you. I had the facts and not the framework. Printing the relevant bit and taking it with me.

Clinical perspective, offered as context rather than as advice. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

I would rather be corrected than agreed with, if it comes to it.
