Title: 
Association of meat consumption with NAFLD risk and liver-related
biochemical indexes in older Chinese: a cross-sectional study
Version: 
0

Reviewer's report:
I reviewed the paper by Peng et. al. describing the association between meat
consumption and NAFLD risk in older Chinese. There are two major concerns
regarding this study:
- It is not justified why the reader expect different results in the Chinese
population compared to other populations as this relationship is well established
(Zelber-Sagi et. al, JHep 2018). It would be interesting if the authors stratified
their analysis based on BMI/ lean NAFLD or presence of Type 2 DM.
- The authors did not adjust for important confounders such as saturated fat diet,
high carb diet or cholesterol intake.
