This is specifically for an annual screening of women 40-49yrs. The reason why this article was written is because there is a scientific debate about whether the advantages outweigh the disadvantages in this age group. I don't think this article really settles this discussion. When you look at the CI you'll see it's rather big and the upper bound is only slightly below 1. But this is about screening of rather young women. Most established screening programs start at an age of 50. Still young. :-)
