Title: The association between physical activity and risk of gastric cancer; an umbrella review
Version: 1 Date: 13 Jun 2024
Reviewer's report:
The present manuscript is an overview of systematic reviews assessing the relationship between
physical activity and gastric cancer. Overall, it is a well-written and relevant article. Minor

Eligibility criteria:
More information regarding the inclusion criteria needs to be provided, i.e. what kind of
systematic reviews were included. Systematic reviews of RCTs, of observational studies, or
both? Furthermore, did you include every systematic review or was there a minimum of studies
that should have been included?
Search methods:
1. I suppose "in November 13, 2022" means until that date? Please clarify (e.g. from inception
to November 13, 2022).
2. An update of the literature search is necessary, as 1,5 year has passed since the search date.
3. The supplementary material is not provided. Please provide the search algorithm.
Search results and screening process:
A list of the excluded full-text studies needs to be provided along with the reasons for exclusion.
Discussion:
Are there any other individual studies (not included in a systematic review) in the field? If so,
please state why they were not included in your review.
Table 1:
Please add a column with the study types that were included in each review (e.g. RCT, cohort,
case-control, etc.)
TYPOS
Abstract: "A systematic search was performed in PubMed, Scopus, Web of Science, and
ProQuest databases in November 13, 2022 through databases with predefined keywords." Please
remove "through databases" for clarity.
Discussion: The sentence beginning with "5 systematic reviews on the effect of physical
activities respectively" looks incomplete.
There are other minor language errors as well. Please correct the text very carefully.
