The study answers the research question and the methods are appropriate. It is in line with the scientific evidence available on this test and the studies that have been carried out, although there are still few controlled clinical trials available. This study corresponds to the designed cohorts and provides a large sample, in line with simulations with a high degree of reliability (MISCAN-colon).
Limitations are clearly specified in the study.
The use of FIT in screening seems to be consistent in terms of acceptability, although the causes of inequalities should be investigated further.
