Yeah, I thought the discussion of how you couldn't just directly compare people that accepted the colonoscopy invitation with the control group was really interesting, and non-obvious (at least to people like me that don't design studies). It reminds me of the fundamental problem that all surveys have in terms of the bias introduced by being limited to "people who agree to take surveys".
- Nevermark 3y agoAny self-selection where higher risk individuals opt-in more, increases benefit/cost ratios. That seems like a pro invitation argument. (I.e. pro treatment for the invited + opt-in cohort.)
- rocqua 3y agoBut alternative screenings with a wider acceptance could have a higher 'benefit-cost' for a lower 'benefit/cost'.
