Reviewer's report:  
 
In the paper entitled "Quality of life in people with coeliac disease before and after diagnosis: a 
UK population -based longitudinal perspective", the authors reported and compared two surveys 
on the impact of celiac diagnosis on patients'life conducted in  2006 and 2015. It is an interesting 
topic and a well written paper, however, the reviewer believes that the work needs minor 
essential revisions which are reported below:  
- The title and most of the paper are only focused on quality of life, however the s urvey 
analysed several aspects of the patients 'life. So, the reviewer believes that the title and part 
of the text should be more related to all study's aims: symptoms, costs, limitations, dietary 
compliance etc. Possible title could be "the impact of coe liac diagnosis on patients'life" for 
example.  
 
- In the methods, the authors should add two separated paragraphs reporting the information 
of Table 1 with more details on both surveys and both study populations. At this time, data 
on 2006 survey are not cl ear.  Are the study population the same?  
 
- The multiple comparisons between survey 2006 and survey 2015 made reading difficult. 
Please try to simplify all the information in the text.  
 
- Are data regarding 2006 survey published anywhere?     
Are the methods appropriate and well described?
