The study does not say that coloscopies don't help. The study measures a difference in the study's population. The study does indicate they don't affect outcomes as much as expected. However, their affect is positive.

The study's measured affect has wide errors bars indicating a larger sample size is needed. Subsequent studies could show the affect is more inline with expectations but are unlikely to show less affect.

The question as to whether this will be used to reinforce hesitancy for this procedure; we can already see it in the comment. Logic and reason are not naturally occurring traits. I predict this will be used to move more people into the control group. Going against medical advice is anecdotally meaningful.
