Title: FARKOR: Evaluating the effects of a risk -adapted screening program for familial 
colorectal  cancer in individuals between 25 and 50 years of age in a prospective population -
based  intervention study  
 
Version: 1 Date: 27 Feb 2020  
 
Reviewer: Isabel Portillo  
 
Reviewer's report:  
 
I consider your manuscript has improved but I would like to consider:  
 
1) Are the physicians respon sible to recruit and follow -up the patients?  
2) Who inform the patients and collect the Informed Consent?  
3) The code C21 is not included in CRC  
4) The follow -up of participants should be clarified, because one result will be not 
enough to estimate the i mpact. (5y -10y) 
5) How do you check the results of non -participants?  
Thanks a lot
