This is an interesting study which focuses on the different aspects of diet and risk of NAFLD.
There is lots of evidence investigating effects of dietary factors on many diseases, but have a
glance to diet quality index is so appreciable.
However, there are some issues need minor revision that may improve your paper:
1. In the paper (Line 118 and 141), it is mentioned that details of DQI-I and DQI-R calculation
have been described elsewhere. Please determine the reference.  Also, please clarify what do
you mean about empty calorie foods in moderation score?
It is better to explain how to investigate the association between per SD increment and the odds
of NAFLD in statistical analysis.
2. Line 276- page 14: what do you mean? “Also, a meta-analysis of trials showed that weight
loss in the short-term ...” It is not clear. Instead of that sentence, you can imply this finding in
the below sentence:
- A meta-analysis of trials reported no differences in weight, cardiovascular and diabetes risk
factors with two different dietary compositions (low CHO diets vs isocaloric Balanced diets)
which is related to overall balance score.
3. It  would be better to have a general revisit in terms of both language and narrative.
A few lines require rewording / clarification:
- Line 201- page 11; any significant association of per SD increments of … and … with OR…
- Line 271- page 14; among should be changed to between
- Line 281- page 14; “To our knowledge, the present study first assessed…” should be changed
to “To our knowledge, this is the first study...”
- Line 14, page 2; each one SD increment in the DQI-I score was… (OR=0.65) should be changed
to OR=0.63 (according to table 3)
