This is what you were replying to when you said "The placebo effect itself isn't real":

> while a sugar pill doesn't make a tumor disappear, it can be very good at pain management.

And now you go to this version:

> There were some possible minor placebo effects in a few isolated conditions – mostly pain

So is it real or not? We're just saying the same thing, what's the point of saying it doesn't exist and then revert back to exactly what was said originally?
