Version: 1 Date: 23 Jun 2024
Reviewer's report:
Thank you for the opportunity to review this article. The current study focuses on an important
research topic relevant to the scope of BMC Gastroenterology. Overall, the manuscript is
well-written. However, a few minor comments should be addressed before the manuscript is
published.
1. There is too little description related to physical activity in the introduction section. Please
provide an overview of previous studies.
2. Please describe the importance of conducting an umbrella review in the introduction section.
3. Description in the fifth paragraph of the introduction reads like a summary. Please describe
the purpose of this study.
4. As stated in the Search methods section, some time has passed since the search was conducted.
Were there any systematic reviews published after December 2022?
