Re: Effectiveness of flexible sigmoidoscopy screening in men and women and different age groups: pooled analysis of randomised trials

I make the same remark as the previous response: there are no absolute risk reduction figures. Trying to make the calculation, I get the impression that this absolute reduction is at the level of 1% after close to ten years. Which obviously does not carry any interest.

We would all be happy to have the absolute risk reduction provided. For all groups obviously.
