Title: Exercise is inversely associated with functional dyspepsia among a sample of Chinese
male armed police recruits
Version: 0 Date: 23 Oct 2023
Reviewer's report:
Thank you for giving me the opportunity to review the article. The authors conducted a study
focusing on the association between exercise and functional dyspepsia. I thought that the topic is
clinically important, but there are several methodological problems in the manuscript. Therefore,
the reviewer thought the manuscript should be revised before further considerations. I listed my
comments below.
Comments:
Title:
1. The study only included male, and they should mention about this point in the title.
Abstract:
2. The authors mentioned that “the incidence rate of FD in Chinese armed police recruits
was 1.77%”, but the coverage rate of their study is unclear. The incidence rate is only in the
participated population.
Methods:
3. The authors should add the ethical approval number and date.
4. The recruiting process is unclear. The authors should explain about the details.
5. The authors should explain about the sample size calculation.
6. How did the authors select the confounding variables of their analysis?
7. The authors should use the words “ethnicity” and “race” consistently.
8. The population only included 2% of the minority nationality, but they adjusted. Is it required?
9. The age of this population is “19.8±1.5 years”, but they included multivariate analysis. Is it
required?
Results:
10. The authors should add the total number of potential participants of their study. In addition
to this, they should add a flow diagram of this study.
Discussion:
11. The authors should discuss about the “special social groups” in more detail.
12. Could the COVID-19 pandemic affect the study process and the results? The authors
conducted the study in 2021, and they should mention about it.
