Reviewer's report:
- The abstract should state briefly the purpose of the research, the principal
results and major conclusions. An abstract is often presented separately from the
article, so it must be able to stand alone.
- It is suggested to present the structure of the article at the end of the
introduction.
- The necessity and innovation of the article should be presented to the
introduction.
- A flowchart should be added to the article to show the research methodology.
- The major defect of this study is the debate or Argument is not clear stated in
the introduction session. Hence, the contribution is weak in this manuscript. I
would suggest the author to enhance your theoretical discussion and arrives your
debate or argument.
- Sections and sub-sections should be numbered in order.
- More suitable title should be selected for the table 1 instead of "The dietary
modification intervention".
- It is suggested to compare the results of the present research with some similar
studies which is done before.
- Following, you will find some new related references which should be added to
literature review:
Lin An et al. GRIK3 rs490647 is a Common Genetic Variant between
Personality and Subjective Well-being in Chinese Han Population;
Hanscom et al. Polyvagal and Global Cytokine Theory of Safety and Threat
Covid-19 - Plan B.
- Page 10: the following paragraph is unclear, so please reorganize that:
"Non-parametric two-way analysis of variance was conducted to identify
whether there were any significant differences in menstrual pain and urinary
BPA levels from pre-intervention to the first, second, and third menstrual cycles
according to adherence levels. Finally, to explore the significance of changes
among the measured points, the Wilcoxon signed-rank test was conducted as a
post-hoc test."
- It is suggested to add articles entitled "Lamptey et al. Myths and
Misconceptions about Intrauterine Devices: Impact on Usage" and "Kipkorir et
al. Gender Perspective on Drivers of Cigarette Smoking: Two Part Model
Approach" to the literature review.
- Much more explanations and interpretations must be added for the results,
which are not enough.
- Please make sure your conclusions' section underscore the scientific value
added of your paper, and/or the applicability of your findings/results, as
indicated previously. Please revise your conclusion part into more details.
Basically, you should enhance your contributions, limitations, underscore the
scientific value added of your paper, and/or the applicability of your
findings/results and future study in this session.
- DOI of the references must be added (you can use "https://crossref.org/").
