The cross-sectional survey focuses on HRQOL among Chinese seasonal retired migrants in Wuzhishan, Hainan province, China. Given the limited data available, it is important to document these findings.
First, ensure that your title accurately limits the scope to the specific region mentioned.
Second, provide the extended form of EQ-5D-5L in both the main text and abstract upon its initial usage.
Third, consider incorporating a brief review of the healthy migrant effect and the salmon bias hypothesis in the introduction, linking these theories to the health of Chinese seasonal retired migrants (Refer: PMID: 23508367, PMID: 37456617, PMID: 35926662). This would enhance the readers' interest!
Fourth, a brief review of similar HRQOL studies, such as those involving rural-to-urban migrant workers, could further enrich your paper (Refer: PMID: 25403568).
Fifth, your paper's English language usage requires additional editing for clarity. For example, specify the year when there was an increase of a million in line 63. Also, in line 67, identify the 'non-migrants' as either locals or origin people, as the comparative results could differ.
Sixth, health status and HRQOL don't equate; a review on health status in seasonal retired migrants is therefore misplaced in your introduction. Please provide further elucidation on this.
Seventh, as your study period is from October to November 2022, consider the potential influence of the COVID-19 pandemic.
Eighth, assessing migrants' adjustment to the local society is significant. However, it appears this was overlooked in your methodology (Refer: PMID: 27300005).
Ninth, it's essential to mention the limitation of not having a control group of non-migrants, either locals or people of the same origin. Consequently, temper the early conclusions drawn from your study.
Finally, it's noteworthy that the acceptable cut-off score for the Chinese PSQI is 7, not 5.

Abstract
1. Despite its increasing popularity, the evidence on Chinese seasonal migrants. health status is controversial. What makes it controversial? Kindly expatiate. [Line 28-Line 29]
2. Descriptive analyses of the HRQoL profiles, multiple logistic regression models for the factors associated with each dimension of the EQ-5D, and multivariable linear regression model for the factors associated with the EQ visual analogue scale (EQ-VAS) were performed – What is the difference between multiple logistic regression models and multivariable linear regression model? Please, kindly differentiate them and revise them accordingly [Line 36-Line 38]
Introduction
3. The introduction did not include much vital information on the subject matter. The introduction is the place to review other conclusions on the topic. The introduction section should introduce past findings to those who might not have that expertise. The introduction of this study should follow the ‘Funnel Approach’ to scope and review existing studies globally and the study setting. The ‘funnel approach’ is a method of structuring a literature review that moves from the general to the specific. It is a useful way to organize the literature review when one starts with the broader aspects of the topic and gradually narrowing the focus to the specific aspects of the topic, that one makes the author(s) addressing the subject matter in the study. Therefore, this will illustrate the trends, pattens and prevalence rates of the study outcome of interest of this study. Kindly revise. [Line 56 – Line 97]
4. Where are the gaps identified in this study? What has the previous studies have mentioned as regards the outcome(s) of this study? What is the current study saying on the current situation of your study outcome(s)? Always remember that a gap in a research study is an unanswered question or unresolved problem in a field, which reflects a lack of existing research in that space or it can exist when there is a concept or new idea that hasn't been studied at all, when the existing research is outdated or insufficient, or when there is a disagreement, contextual or methodological issue among the researchers. A gap in a research study indicates an opportunity for further investigation and contribution to the scientific knowledge. Kindly revise. [Line 56 – Line 97]

16. Determination of sample size – how did you arrive at 385 sample size for your study? Show it and tell us the sample size determination formula you adopted and give justification for it. How did you arrive at 992 when you have 385 for sample size? Kindly address this. [Line 160 – Line 167] and [Line 192 – Line 193].
17. Discuss the required coefficients for sample size calculations regarding population standard deviation, confidence level, and desired precision. Kindly address this. [Line 162 – Line 163].
18. Provide a detailed information on how you design the research instruments (questionnaires) and show the measurement guidelines of the questionnaire as the instrument for data collection used in this study. Who propounded these instruments? References them and cite studies that have used them to measure the same outcome of interest as it is in your study (either by adopting or adapting).
19. Describe briefly and precisely step by steps, how you used the above adopted or adapted measurement instruments/guidelines to design your study instruments. Show how your variables were measured in the questionnaire.
20. Variable measurements (Outcome variable or Dependent variable) – A dependent variable is the variable that changes as a result of the independent variable (independent or explanatory variables or factors) manipulation. It's the outcome you're interested in measuring, and it “depends” on your independent variable. In statistically analysis, dependent variables are also called ‘response variables’ (they respond to a change in another variable). Therefore, specify your outcome variable very well and show us how it is going to be measured. Is it a binary outcome variable or what? This section should discuss the measurements of the outcome variable or dependent variable(s). Kindly address this.
21. Explanatory Variable or Independent Variable: You did not indicate your independent variables you used in this study. I know that you cannot have the dependent variable without the independent variable when running the statistical analysis. Insert the independent variables and how they are going to be measured (References may be cited). Define all your Explanatory Variables or Independent Variables and how they were measured in your study. This is very important, as it will affect the process and approach of statistical analysis. Kindly address this.
22. How did you measure demographic and behavioral characteristics, BMI, and presence of chronic diseases in this your study? Explain each of the measurements in a separate paragraph under the section Statistical analysis and named this section ‘Variable Measurements’. This should not be included in the statistical analysis section. Kindly address this. [Line 178 – Line 179].
23. Statistical analysis – State and describe the type of statistical analysis suitable for each objective and how they will be analysed in this study. For instance, objective one on respondents’ demographic characteristics was analyzed using univariate analysis (Percentage and frequency including graphs and tables). Objective two measure the associations between the outcome variable and explanatory variables by using the bivariate analysis (Chi-Square or/and Pearson correlation coefficient). Objective three measures the relationship influence between the variables and the predictors of the outcome variable on the explanatory factors, when other factors are kept constant (for instance, when using Logistics regression, if and only if the outcome variable is binary, Yes = 1 and No = 0), otherwise, multiple régression analysis, etc. This section must be revised as it is very important. Also, include the models and equations of the bivariate and inferential statistical analysis in your discussion under the section of the statistical analyses. Kindly address this question.
24. How did your account for missing variables or non-responses from the respondents? Kindly look into this.
25. Where is the “Declaration of Helsinki Ethical principles” of this study? Where is the Ethical Approval? What ethical principles did you employed? Did you follow the set of ethical principles. Where is the informed consent form in Research? How did you address these factors associated with research such as in ensuring in the protection of participants’ rights, ensuring that participants understand the nature and purpose of the research, the risks and benefits of participating, and their rights as participants whether to participate or decline at any time they feel not to. Kindly address this. Was informed consent forms given to the respondents during the data collection?
