Reviewer’ s report
Title: Classification of Gastrointestinal Symptom Patterns in Young Adults
Version: 2Date: 19 Jul 2020
Reviewer's report:Having considered comments from both reviewers, the author's responses are acceptable and
represent an improvement to the quality of the manuscript as befitting publication.
One discretionary revision to add is to state explicitly the number of surveys distributed and thenumber received. The authors mentioned in the response to reviewer comments that there were nonon-respondents, so this needs to be stated in the paper more clearly too.
