> I read it that the invite doesn get you differnces, the colonoscopy itsrlf does. No, it doesn’t, because the two groups of people you’re comparing aren’t actually similar, and therefore any outcome difference can’t be tied to the intervention. The difference in outcome between those two groups may merely be that the people who go through with the colonoscopy (not fun) are also willing to go through with their doctor’s recommendations on, say, diet restrictions (also not as fun!) so are healthier and have better outcomes. |
