Title: Non-Alcoholic Fatty Liver Disease and socioeconomic determinants in an Iranian cohort
study
Version: 1 Date: 06 Apr 2023
Reviewer's report:
Dear editor,
Thank you for choosing me as a reviewer. This manuscript examines the prevalence of non-
alcoholic fatty liver disease and its socio-economic determinants in an Iranian population. It is an
interesting study with a large sample size. However, there are some corrections to the manuscript
that need to be made. My suggestions are as follows
1. The manuscript needs English language editing
2. Keywords: Choose keywords based on the MeSH. Use full names instead of abbreviations.
Non-alcoholic fatty liver disease instead of NAFLD. The name of the place (Hoveyzeh) should
be removed from the keywords.
3. Methods: There is no place for this sentence in the method and it should be in the introduction
"However, the reported association between SES and NAFLD is currently controversial.
Therefore, this study investigated the association between a more comprehensive SES composite
including educational level and qualification, wealth index, Townsend deprivation index, and
NAFLD."
Results:
4.  At the beginning of the analysis, you have to decide how many groups each variable will be,
for example, age. In table 1, as in table 3, divide age into two groups. It is not interesting to have
7 groups in a table and 2 groups in a table.
5. What is meant by cholesterol in table 1? Cholesterol disorder? If yes, it is not defined in the
method. Why didn't you report dyslipidemia? or the average of 4 lipid profile items
6. What is the definition of diabetes? It is not defined in the method.
7. In the method, it should be fully explained what do you mean by negative and positive
NAFLD? And what is the range of the FLI index?
8. I have a question; why did you exclude people with an index of 30 to 59?! You could also
report the status of this normal group in Tables 1 and 2 and see its difference with the other two
groups and finally consider the outcome variable in quantitative regression.
9. In addition, you said in the method that people with an index of 30 to 59 were excluded, and
in the findings you reported 30 to 60?! Which is correct?
10. When you define abbreviations at the beginning of the introduction, you should use that
abbreviation instead of the full name until the end of the manuscript. You used the full name
of NAFLD many times.
11. I suggest to merge table 3 and 4 so that the difference between crude and adjusted model
clearly defined for the readers.
12. I suggest you divide the age into two groups. The reason is that in Tables 3 and 4, there
was an inverse relationship between those over 60 years old. This may be due to the smaller
population of the over 60 age group compared to the other two groups
