Title: The relationships between IBS and perceptions of physical and mental health – a
Norwegian twin study
Version: 1 Date: 24 Apr 2022
Reviewer's report:
The relations between IBS and perceptions of physical and mental health - a twin Norwegian
study, addresses an interesting topic but presents important limitations.
The study carried out in 2014-2015 by means of a questionnaire sent by mail, should mention
the criteria of Rome III still valid in that period and not those of Rome IV published in
2016( limitation page19).
As reported by the authors themselves, the diagnosis of IBS was predominantly self-reported
and therefore unreliable as the exclusion of warning symptoms or concomitant somatic diseases.
Another important limitation is the lack of an adequate sample size.
Finally, the authors did not explain the reason for the exclusion of a population group between
20-40 years that could have had more IBS patients.
