Reviewer’s report
Title: 
Patient experiences with the role of physical activity in inflammatory bowel disease: results from a
survey and interviews
Version: 
1 
Date: 
12 Mar 2021
Reviewer's report:
I congratulate the authors for addressing all of the issues. However, regarding the medication and
procedures, 
I would suggest to add in the manuscript how this data was collected (from the survey) as a
limitation of the study, since this information was not verified with the medical records. As well, the
authors may want to add the response to one reviewer's comment regarding compliance to the exercises
("We agree that self-reported data is a limitation of this study. However, we expect that this does not
influence the association since compliance applies to all participants at all times and in case everybody has
for example overestimated their level of physical activity by 10%, the association will remain the same").
