Reviewer's report:  
 
The Authors conducted a survey of members of Beyond Celiac, a national patient advocacy 
groups in USA, collecting responses from a large number of adults who reported having celiac 
disease, evaluating dietary adherence, disease -specific symptoms, and quality of life and  
association with healthcare provider follow -up in celiac disease. The research original, novel and 
the Authors have done a good job, especially for the number of respondents. Methodology is 
accurate. General logic and justification  of interpretations and conclusions are obvious.  
The same authors suggest the limitations of the study. It could suffer from self -selection bias 
based on who received notification of the survey; the information are reported by patients and 
there is no doc umentation for controlling the veracity of the data;  the study is cross -sectional 
and observational, so it is not possible to determine causality in the associations observed. These 
are essential limitations, but it cannot be left out of the large number of participants.  
Supplementary material  
Figure S4: It is amazing that autoimmune thyroiditis does not appear in autoimmune diseases 
related with celiac disease, because the presence of CD  could favor the appearance of 
autoimmune thyroiditis (Naiyer AJ et al. Tissue transglutaminase antibodies in individuals with 
celiac disease bind to thyroid follicles and extracellular matrix and may contribute to thyroid 
dysfunction. Thyroid 2008; 18:1171 -8; Leerner A et al.Gut -thyroid axis and celiac disease.
