Title: Dietary habits and obesity indices in patients with gastro-esophageal reflux disease: a
comparative cross-sectional study
Version: 0Date: 08 Jul 2017
Reviewer: Elias Athanasakis
Reviewer's report:
Page 4, line14: "The persistence of these symptoms…" Please rephrase. The persistence of
symptoms can impair quality of life but symptoms cannot develop extra-esophageal problems. Thepersistence of GERD can produce further extraesophageal problems.Page 4, line 27: "Althoughthe role of some of these factors…" Dietary habits may closely relate to obesity and consequentlyto the development of GERD. Please comment on that.Page 4, line 49: please add "and" betweenthe words "smoking" "obesity".Page 5, line 32: explain why the eligibility criteria includedpatients between the age of 20 and 60.It would be interesting if the authors can give an explanationfor the positive relation between marital status and GERD.
